WEBVTT 00:00:00.000 --> 00:00:03.859 Okay, I want you to take a second and Mentally 00:00:03.859 --> 00:00:06.320 put yourself in a specific place. Right. You 00:00:06.320 --> 00:00:08.500 are sitting at a big polished desk. Maybe it's 00:00:08.500 --> 00:00:10.460 mahogany. The air conditioning is humming just 00:00:10.460 --> 00:00:12.859 a little too loudly. I can picture it. And there's 00:00:12.859 --> 00:00:15.519 a person in a suit across from you sliding a 00:00:15.519 --> 00:00:17.920 thick stack of papers your way. They hand you 00:00:17.920 --> 00:00:21.059 a pen. The moment of truth. Exactly. You're about 00:00:21.059 --> 00:00:23.879 to sign a contract. Maybe it's for a house. Could 00:00:23.879 --> 00:00:26.300 be a car. Maybe a business loan. And your eyes 00:00:26.300 --> 00:00:28.780 drift down to the bottom of the page to that, 00:00:28.780 --> 00:00:31.379 you know, that dense block of tiny text that 00:00:31.379 --> 00:00:33.920 nobody actually reads. The terms and conditions 00:00:33.920 --> 00:00:37.619 zone. The fine print. The danger zone. And buried 00:00:37.619 --> 00:00:40.560 deep in that text is a word. I'm going to say 00:00:40.560 --> 00:00:42.479 the word, and I want you to be honest about your 00:00:42.479 --> 00:00:45.359 immediate visceral reaction. Ready? I'm ready. 00:00:46.259 --> 00:00:51.159 Amortization. Right. That is the correct reaction. 00:00:51.340 --> 00:00:53.140 It's the kind of word that just makes your eyelids 00:00:53.140 --> 00:00:55.380 feel heavy hearing it. It does. It sounds like 00:00:55.380 --> 00:00:58.100 dust. It sounds like a room full of people in 00:00:58.100 --> 00:01:00.979 beige cardigans quietly clicking calculators 00:01:00.979 --> 00:01:03.619 in a basement somewhere. It definitely has a 00:01:03.619 --> 00:01:06.819 reputation. It feels like pure, unadulterated 00:01:06.819 --> 00:01:10.319 administrative filler. You know, it's the kind 00:01:10.319 --> 00:01:12.579 of financial jargon that feels designed to keep 00:01:12.579 --> 00:01:15.109 normal people out of the room. Totally. Like, 00:01:15.150 --> 00:01:17.430 don't worry your pretty little head about this. 00:01:17.469 --> 00:01:19.909 Let the professionals handle the amortization. 00:01:20.010 --> 00:01:22.609 Right. It's intimidating on purpose. It sounds 00:01:22.609 --> 00:01:26.620 terrifyingly dry. But and this is the big but 00:01:26.620 --> 00:01:29.459 that is driving our whole deep dive today. We 00:01:29.459 --> 00:01:31.739 did the digging. We did. We pulled the source 00:01:31.739 --> 00:01:35.500 material, which was essentially a disambiguation 00:01:35.500 --> 00:01:38.640 of this one concept across multiple fields. And 00:01:38.640 --> 00:01:41.079 we found something that honestly, it shocked 00:01:41.079 --> 00:01:43.299 me. It was a genuine surprise for sure. This 00:01:43.299 --> 00:01:46.540 word amortization is not just one thing. It isn't 00:01:46.540 --> 00:01:49.079 just a boring banking term. Not even close. It 00:01:49.079 --> 00:01:51.819 is a shapeshifter. It is a concept that seems 00:01:51.819 --> 00:01:55.140 to like jump from one reality to another, changing 00:01:55.140 --> 00:01:57.420 its outfit, but keeping its soul. That's a great 00:01:57.420 --> 00:01:59.900 way to put it. We found it in the obvious places, 00:01:59.959 --> 00:02:02.060 you know, like personal loans. But then it popped 00:02:02.060 --> 00:02:04.120 up in corporate accounting, which is distinct. 00:02:04.280 --> 00:02:06.000 A little different. Yeah. Then we found it in 00:02:06.000 --> 00:02:08.039 tax law, which is a whole other beast entirely. 00:02:08.340 --> 00:02:10.280 Yeah. And then, and this is where I did a double 00:02:10.280 --> 00:02:12.699 take, we found it in computer science. Algorithms. 00:02:13.280 --> 00:02:15.620 Algorithms. And finally, to top it all off, we 00:02:15.620 --> 00:02:19.379 found it in urban planning and zoning. Which 00:02:19.379 --> 00:02:22.020 is just wild. I mean, how does the same single 00:02:22.020 --> 00:02:25.479 word describe paying off your mortgage, executing 00:02:25.479 --> 00:02:28.400 a line of computer code, and determining when 00:02:28.400 --> 00:02:31.520 a building is illegal? It seems completely disconnected, 00:02:31.659 --> 00:02:34.379 right? But the more we looked at the actual definitions 00:02:34.379 --> 00:02:36.300 in the source material, the more we realized 00:02:36.300 --> 00:02:39.240 that while the contexts are wildly different, 00:02:39.360 --> 00:02:41.620 I mean... A microchip has absolutely nothing 00:02:41.620 --> 00:02:44.099 in common with a brick wall. Nothing. The underlying 00:02:44.099 --> 00:02:46.840 philosophy is identical. It reveals a very, very 00:02:46.840 --> 00:02:49.819 specific way that humans have figured out how 00:02:49.819 --> 00:02:52.360 to deal with reality. So that is our mission 00:02:52.360 --> 00:02:55.159 today. We are going to go on a journey through 00:02:55.159 --> 00:02:57.960 these five worlds. We're going to map this shapeshifter. 00:02:57.960 --> 00:03:00.400 We're going to connect the dots between the execution 00:03:00.400 --> 00:03:05.560 cost of an algorithm and the non -conforming 00:03:05.560 --> 00:03:08.280 use of a city lot. And I think by the end of 00:03:08.280 --> 00:03:10.300 this, you, the listener, are going to realize 00:03:10.300 --> 00:03:13.280 that amortization isn't really about math. It's 00:03:13.280 --> 00:03:16.759 about time. It's about how we handle the fact 00:03:16.759 --> 00:03:18.800 that we just can't do everything all at once. 00:03:18.939 --> 00:03:21.000 I love that. Okay, let's unpack this. We have 00:03:21.000 --> 00:03:23.500 to start on the ground floor. The place where 00:03:23.500 --> 00:03:25.699 pretty much everyone listening has probably seen 00:03:25.699 --> 00:03:27.979 this word, even if they just skimmed right past 00:03:27.979 --> 00:03:31.840 it. The bank. The bank. The daily grind of the 00:03:31.840 --> 00:03:35.020 loan. The classic context. So looking at the 00:03:35.020 --> 00:03:37.219 source material for amortization in the context 00:03:37.219 --> 00:03:39.879 of loans, we get a definition that is surprisingly 00:03:39.879 --> 00:03:45.539 specific. It says, decreases over the life of 00:03:45.539 --> 00:03:48.520 an amortizing loan. It's a short sentence, but 00:03:48.520 --> 00:03:50.979 every single one of those words is doing some 00:03:50.979 --> 00:03:53.800 really heavy lifting. Let's break it down because 00:03:53.800 --> 00:03:55.960 I think most people have a vague idea of what 00:03:55.960 --> 00:03:58.139 this means, but the mechanics of it are actually 00:03:58.139 --> 00:04:01.740 fascinating. First up, loan principle. Why does 00:04:01.740 --> 00:04:04.360 the definition obsess over the principle? This 00:04:04.360 --> 00:04:06.300 is the crucial distinction that trips people 00:04:06.300 --> 00:04:08.439 up. When you write a check for your mortgage, 00:04:08.659 --> 00:04:11.919 you think, I am paying off my house, but you 00:04:11.919 --> 00:04:14.780 aren't. Not entirely. Not entirely. You're fighting 00:04:14.780 --> 00:04:18.860 a war on two fronts. You have the interest, which 00:04:18.860 --> 00:04:22.100 is basically the rent you pay to the bank for 00:04:22.100 --> 00:04:24.100 the privilege of using their money. Okay, that's 00:04:24.100 --> 00:04:25.680 front number one. And then you have the principal, 00:04:25.879 --> 00:04:28.240 which is the actual mountain of money you borrowed 00:04:28.240 --> 00:04:31.480 in the first place. And amortization is specifically 00:04:31.480 --> 00:04:34.779 about the second one. 100%. Amortization is the 00:04:34.779 --> 00:04:37.639 mechanism of attacking the principal. If you 00:04:37.639 --> 00:04:40.600 have a loan where you are only paying interest... 00:04:40.860 --> 00:04:42.560 And those exist. They're called interest -only 00:04:42.560 --> 00:04:45.180 loans. You are not amortizing. You're just running 00:04:45.180 --> 00:04:47.899 in place. You're treading water. You could pay 00:04:47.899 --> 00:04:50.160 an interest -only loan for 50 years, and on the 00:04:50.160 --> 00:04:52.680 last day, you would still owe the exact same 00:04:52.680 --> 00:04:55.259 amount you borrowed on day one. That is a terrifying 00:04:55.259 --> 00:04:57.279 thought. You're just renting the money forever. 00:04:57.519 --> 00:05:00.540 Exactly. Amortization implies movement. It implies 00:05:00.540 --> 00:05:03.620 progress, which leads directly to the next key 00:05:03.620 --> 00:05:06.860 word in that definition, decreases. The process 00:05:06.860 --> 00:05:10.040 by which loan principal decreases. The directionality 00:05:10.040 --> 00:05:12.470 is key. It's a guaranteed downward trajectory. 00:05:12.670 --> 00:05:15.230 It implies that there is a finite amount of debt, 00:05:15.389 --> 00:05:17.870 and there is a mathematical machine in place 00:05:17.870 --> 00:05:20.850 to ensure that that amount gets smaller every 00:05:20.850 --> 00:05:24.279 single month. No exceptions. It feels obvious, 00:05:24.399 --> 00:05:26.139 but when you compare it to other forms of debt, 00:05:26.259 --> 00:05:28.220 it's actually really special. I mean, think about 00:05:28.220 --> 00:05:30.560 credit cards. Oh, credit cards are the anti -amortization 00:05:30.560 --> 00:05:33.259 in some ways. Right. You can pay the minimum 00:05:33.259 --> 00:05:35.199 due on a credit card, and because of how the 00:05:35.199 --> 00:05:37.660 math works, your balance might barely move. Or 00:05:37.660 --> 00:05:40.279 it might even go up if you keep spending. There's 00:05:40.279 --> 00:05:42.980 no built -in guarantee that it hits zero on a 00:05:42.980 --> 00:05:45.399 specific date. It could go on forever. But an 00:05:45.399 --> 00:05:47.579 amortizing loan is different? I like to think 00:05:47.579 --> 00:05:49.939 of an amortizing loan as a suicide pact for the 00:05:49.939 --> 00:05:54.240 debt. A suicide pact. That's dark. It is. The 00:05:54.240 --> 00:05:56.439 loan is designed to kill itself. From the moment 00:05:56.439 --> 00:05:58.680 you sign the papers, the math is locked in. The 00:05:58.680 --> 00:06:01.100 amortization schedule is created and it says 00:06:01.100 --> 00:06:05.740 in 360 months or 180 months for a 15 -year loan, 00:06:05.959 --> 00:06:09.040 this balance will be zero. It's inevitable. It's 00:06:09.040 --> 00:06:11.600 a countdown clock. But here's the part that I 00:06:11.600 --> 00:06:13.540 think is the real magic trick of amortization. 00:06:14.060 --> 00:06:16.240 And the source material alludes to this with 00:06:16.240 --> 00:06:18.439 the word process. The payment stays the same. 00:06:18.560 --> 00:06:20.879 Right. This is what confuses so many first -time 00:06:20.879 --> 00:06:23.180 homebuyers. You get a mortgage and the bank says, 00:06:23.319 --> 00:06:26.639 OK, your payment is, say, $2 ,000 a month. And 00:06:26.639 --> 00:06:29.920 that stays $2 ,000 a month for 30 years, assuming 00:06:29.920 --> 00:06:31.959 a fixed rate, of course. But what is happening 00:06:31.959 --> 00:06:34.579 inside that $2 ,000 payment is shifting violently 00:06:34.579 --> 00:06:37.060 over time. Violently is a good word for it. It's 00:06:37.060 --> 00:06:39.970 a dramatic change. that happens very, very slowly. 00:06:40.350 --> 00:06:42.370 Walk us through that shift because I think this 00:06:42.370 --> 00:06:44.670 is where the process part really shines. Okay, 00:06:44.689 --> 00:06:47.790 so month one, you just bought your house. You 00:06:47.790 --> 00:06:50.310 send in your $2 ,000. You feel great. You think, 00:06:50.310 --> 00:06:52.910 I just knocked $2 ,000 off my debt, but you didn't. 00:06:52.930 --> 00:06:55.269 Not even close. Not even close because the bank 00:06:55.269 --> 00:06:57.009 takes their cut first. In the beginning, your 00:06:57.009 --> 00:06:59.269 principal balance is huge. Let's say you borrowed 00:06:59.269 --> 00:07:02.430 $500 ,000. So the interest on that huge balance 00:07:02.430 --> 00:07:05.829 is very high. Out of your $2 ,000 check, the 00:07:05.829 --> 00:07:09.050 bank might keep $1 ,900 as pure interest. Ouch. 00:07:09.089 --> 00:07:11.670 So only $100 actually goes to the principal. 00:07:11.870 --> 00:07:14.069 To the mountain. Exactly. You just chipped a 00:07:14.069 --> 00:07:17.990 measly $100 off a $500 ,000 mountain. It feels 00:07:17.990 --> 00:07:19.829 hopeless. I'd be so depressed seeing that on 00:07:19.829 --> 00:07:22.449 a statement. But, and here is the genius of the 00:07:22.449 --> 00:07:25.810 system, because you paid that $100, the principal 00:07:25.810 --> 00:07:30.029 is now $499 ,900. It's slightly smaller. Just 00:07:30.029 --> 00:07:32.709 a tiny bit smaller. Which means next month, the 00:07:32.709 --> 00:07:34.740 interest calculation is based... on a slightly 00:07:34.740 --> 00:07:37.079 smaller number. So maybe the interest is only 00:07:37.079 --> 00:07:41.439 $1 ,899. Which leaves $101 for the principal. 00:07:41.639 --> 00:07:43.639 You got it. It accelerates. So it's a snowball 00:07:43.639 --> 00:07:45.579 rolling downhill. That's the perfect analogy. 00:07:45.879 --> 00:07:48.920 It starts agonizingly slow. For the first few 00:07:48.920 --> 00:07:51.339 years, you're barely making a dent. But every 00:07:51.339 --> 00:07:54.060 single month, the interest slice of the pie shrinks. 00:07:54.399 --> 00:07:56.560 And the principal slice grows. Until what? At 00:07:56.560 --> 00:07:58.319 the end, it's flipped. Completely flipped. By 00:07:58.319 --> 00:07:59.740 the time you get to the last year of the loan, 00:07:59.899 --> 00:08:02.620 that same $2 ,000 check you send in is almost 00:08:02.620 --> 00:08:05.959 entirely principal. Maybe you own $1 ,950 goes 00:08:05.959 --> 00:08:09.000 to principal and only $50 goes to interest. You 00:08:09.000 --> 00:08:11.000 are smashing the debt to pieces in those final 00:08:11.000 --> 00:08:13.319 years. I really like the phrase the source used, 00:08:13.500 --> 00:08:16.259 the life of the loan. It's surprisingly poetic 00:08:16.259 --> 00:08:18.600 for a financial dictionary, isn't it? It really 00:08:18.600 --> 00:08:21.240 is the life of the loan. It treats the debt like 00:08:21.240 --> 00:08:23.860 a living, breathing creature. It has a biology. 00:08:24.079 --> 00:08:26.699 In a way, it is. It has a birth. That's the day 00:08:26.699 --> 00:08:28.680 you sit at that mahogany desk inside the papers. 00:08:28.980 --> 00:08:32.860 It has a lifespan, the term, maybe 15 or 30 years. 00:08:33.159 --> 00:08:35.879 And ideally, it has a death, the day the balance 00:08:35.879 --> 00:08:39.000 finally hits zero. And amortization is the aging 00:08:39.000 --> 00:08:41.500 process of that creature. That's it. It's a story 00:08:41.500 --> 00:08:43.240 of its life from beginning to end, written in 00:08:43.240 --> 00:08:46.039 numbers. So when we talk about amortization and 00:08:46.039 --> 00:08:47.879 personal finance, we aren't just talking about 00:08:47.879 --> 00:08:50.500 paying back. We're talking about a structure, 00:08:50.720 --> 00:08:53.940 a deliberate process. It turns a mountain of 00:08:53.940 --> 00:08:55.940 debt so massive you could never pay it today 00:08:55.940 --> 00:08:59.659 into a gentle slope. A slope you can walk up 00:08:59.659 --> 00:09:02.120 one step at a time. That's the real utility of 00:09:02.120 --> 00:09:04.419 it. Without amortization, homeownership would 00:09:04.419 --> 00:09:07.039 be impossible for 99 % of people. For sure. Who 00:09:07.039 --> 00:09:09.740 has $500 ,000 cash just lying around? Almost 00:09:09.740 --> 00:09:12.500 nobody. Amortization creates a bridge across 00:09:12.500 --> 00:09:15.220 time. It says you don't have the money now, but 00:09:15.220 --> 00:09:17.179 you will have the money over the next 30 years. 00:09:17.659 --> 00:09:20.100 Let's construct a math problem that solves for 00:09:20.100 --> 00:09:23.139 that exact reality. It smooths out the impact. 00:09:23.399 --> 00:09:25.980 Instead of being crushed by the mountain, you 00:09:25.980 --> 00:09:28.000 just chip away at it with a small hammer every 00:09:28.000 --> 00:09:31.120 month for a long, long time. Precisely. So when 00:09:31.120 --> 00:09:34.059 you see amortization schedule on your bank statement, 00:09:34.299 --> 00:09:37.139 don't let your eyes glaze over. Think of it as 00:09:37.139 --> 00:09:40.399 the process of decrease. It is the machine that 00:09:40.399 --> 00:09:42.779 is slowly, methodically killing your debt for 00:09:42.779 --> 00:09:46.139 you. Slowly but surely. OK, so that is the money 00:09:46.139 --> 00:09:48.259 we owe. That's the liability side of the balance 00:09:48.259 --> 00:09:50.960 sheet. Now I want to pivot. We're going to leave 00:09:50.960 --> 00:09:53.440 the bank lobby and go into the back office. The 00:09:53.440 --> 00:09:56.039 world of corporate accounting. Right. The invisible 00:09:56.039 --> 00:09:58.200 value. The definition in the source material 00:09:58.200 --> 00:10:01.220 shifts here and it gets a little more jargon 00:10:01.220 --> 00:10:04.980 heavy. It says. amortization accounting the expensing 00:10:04.980 --> 00:10:07.779 of acquisition cost minus the residual value 00:10:07.779 --> 00:10:11.100 of intangible assets in a systematic manner shoo 00:10:11.100 --> 00:10:13.779 yeah there's a lot to unpack there there really 00:10:13.779 --> 00:10:17.000 is we moved from owing money to expensing money. 00:10:17.220 --> 00:10:21.299 And we moved from loans to something called intangible 00:10:21.299 --> 00:10:24.580 assets. What is the big shift in thinking here? 00:10:24.759 --> 00:10:26.220 Well, in the loan example, we were talking about 00:10:26.220 --> 00:10:28.000 a liability, something you have to get rid of 00:10:28.000 --> 00:10:30.279 that's a negative on your books. Something bad. 00:10:30.539 --> 00:10:33.679 Here we are talking about assets, things you 00:10:33.679 --> 00:10:37.159 own, things that have value. But the source is 00:10:37.159 --> 00:10:41.320 very specific. Intangible assets. Intangible, 00:10:41.379 --> 00:10:44.860 meaning things I can't touch. Exactly. This is 00:10:44.860 --> 00:10:46.639 a crucial distinction in the world of accounting. 00:10:47.120 --> 00:10:50.080 If a company buys a new delivery truck, that's 00:10:50.080 --> 00:10:52.200 a tangible asset. You can go out and kick the 00:10:52.200 --> 00:10:55.399 tires. It exists in physical space. As that truck 00:10:55.399 --> 00:10:57.740 gets old and rusty and the engine starts to fail, 00:10:57.899 --> 00:11:00.480 accountants have to track that loss of value 00:11:00.480 --> 00:11:02.500 on their books. But they don't call it amortization. 00:11:02.580 --> 00:11:05.120 They call it depreciation. Okay, so physical 00:11:05.120 --> 00:11:08.740 stuff, depreciation. You got it. But companies 00:11:08.740 --> 00:11:10.639 buy a lot of valuable things that aren't physical. 00:11:10.970 --> 00:11:12.710 What if you're a pharmaceutical company and you 00:11:12.710 --> 00:11:15.169 buy a patent for a new drug? Can't kick the tires 00:11:15.169 --> 00:11:17.090 on a patent. What if you're a media company and 00:11:17.090 --> 00:11:19.529 you buy the copyright to a huge catalog of songs? 00:11:20.029 --> 00:11:22.269 Or what if you buy a competitor just to get their 00:11:22.269 --> 00:11:24.509 well -known brand name? You can't touch a brand 00:11:24.509 --> 00:11:26.629 name. You can't. It's invisible. It lives in 00:11:26.629 --> 00:11:28.929 people's minds. That is an intangible asset. 00:11:29.370 --> 00:11:33.009 But, and this is the key, you still paid a lot 00:11:33.009 --> 00:11:35.450 of very real money for it. And just like the 00:11:35.450 --> 00:11:38.070 truck, it doesn't last forever. Right. Its value 00:11:38.070 --> 00:11:40.669 decays, just not in a physical way. How does 00:11:40.669 --> 00:11:43.370 a patent not last forever? I mean, it doesn't 00:11:43.370 --> 00:11:46.870 rust. It doesn't rust, but it expires. A patent 00:11:46.870 --> 00:11:49.870 has a specific legal lifespan, usually 20 years. 00:11:50.470 --> 00:11:53.809 After that, it's public domain. Or think about 00:11:53.809 --> 00:11:56.470 a big software license. You might buy the rights 00:11:56.470 --> 00:11:59.629 to a piece of software, but in five years, it's 00:11:59.629 --> 00:12:03.250 going to be completely obsolete. The value decays. 00:12:03.820 --> 00:12:06.059 Just not in a way you can see. So you have this 00:12:06.059 --> 00:12:08.059 invisible thing you paid millions of dollars 00:12:08.059 --> 00:12:11.039 for and its value is slowly evaporating into 00:12:11.039 --> 00:12:13.720 thin air. Exactly. And that brings us to the 00:12:13.720 --> 00:12:16.679 math that was embedded in that definition. Acquisition 00:12:16.679 --> 00:12:20.179 cost minus residual value. Let's break that formula 00:12:20.179 --> 00:12:22.559 down. Acquisition cost is simple enough. That's 00:12:22.559 --> 00:12:24.120 what you wrote the check for. Right. Let's say 00:12:24.120 --> 00:12:26.440 our pharmaceutical company buys that patent for 00:12:26.440 --> 00:12:29.299 a cool $20 million. That's the acquisition cost. 00:12:29.480 --> 00:12:31.840 Okay. And residual value is what it's worth at 00:12:31.840 --> 00:12:34.559 the very end of its life. Exactly. With the truck, 00:12:34.700 --> 00:12:36.620 maybe after 10 years you can sell it for scrap 00:12:36.620 --> 00:12:39.720 metal for $500. That's its residual value. But 00:12:39.720 --> 00:12:42.379 with a patent, when it expires? It's worthless. 00:12:42.500 --> 00:12:45.500 Anyone can copy the drug. The competitive advantage 00:12:45.500 --> 00:12:48.419 is gone. So the residual value is usually zero. 00:12:48.659 --> 00:12:52.639 So the math is $20 million you paid minus zero. 00:12:53.100 --> 00:12:55.799 You have $20 million of value that is guaranteed 00:12:55.799 --> 00:12:58.879 to vanish over the life of the patent. And amortization 00:12:58.879 --> 00:13:01.980 is the process of recording that vanishing act 00:13:01.980 --> 00:13:04.740 on your accounting books. You can't just pretend 00:13:04.740 --> 00:13:07.019 you still have a $20 million asset on your books 00:13:07.019 --> 00:13:08.940 the day before the patent expires. That would 00:13:08.940 --> 00:13:11.120 be lying to your investors. You have to show 00:13:11.120 --> 00:13:13.620 it losing value over time. You have to slowly, 00:13:13.879 --> 00:13:17.080 methodically reduce the value on your books to 00:13:17.080 --> 00:13:19.580 match reality. The definition used a phrase I 00:13:19.580 --> 00:13:22.460 really stuck on, in a systematic manner. I love 00:13:22.460 --> 00:13:24.360 that phrase. It sounds so bureaucratic and boring, 00:13:24.500 --> 00:13:26.960 but it's actually about protection. Protection. 00:13:27.120 --> 00:13:30.139 Protection from what? From chaos. From fraud. 00:13:30.600 --> 00:13:32.840 Imagine if there were no rules for this. Imagine 00:13:32.840 --> 00:13:35.500 if a CEO could wake up one morning and say, hey, 00:13:35.600 --> 00:13:37.559 you know what? We didn't make much profit this 00:13:37.559 --> 00:13:39.879 quarter. It looks bad. I know. Let's just not 00:13:39.879 --> 00:13:42.120 record any amortization expense on that patent 00:13:42.120 --> 00:13:44.139 this year. We'll just pretend it didn't lose 00:13:44.139 --> 00:13:47.480 any value. They could inflate their profits artificially 00:13:47.480 --> 00:13:50.740 just by deciding not to. Exactly. Or the opposite. 00:13:51.139 --> 00:13:53.360 Hey, we made too much money this quarter and 00:13:53.360 --> 00:13:55.799 we don't want to pay high taxes. Let's write 00:13:55.799 --> 00:13:58.320 off the entire patent right now to make our profit 00:13:58.320 --> 00:14:01.019 look smaller. That would be just as bad. The 00:14:01.019 --> 00:14:04.080 phrase systematic manner means you can't do that. 00:14:04.159 --> 00:14:05.980 You have to pick a schedule and stick to it. 00:14:06.039 --> 00:14:08.860 It has to be predictable and consistent. Just 00:14:08.860 --> 00:14:11.019 like the loan had a schedule, the asset has a 00:14:11.019 --> 00:14:13.220 schedule. Precisely. The most common method is 00:14:13.220 --> 00:14:15.340 called straight line. You take that $20 million, 00:14:15.659 --> 00:14:17.559 you divide it by the 20 years of the patent's 00:14:17.559 --> 00:14:21.100 life, and you record a $1 million expense every 00:14:21.100 --> 00:14:24.539 single year, rain or shine. That is systematic. 00:14:24.899 --> 00:14:27.779 So if the loan world was about... killing a debt 00:14:27.779 --> 00:14:31.299 over time. The accounting world is about consuming 00:14:31.299 --> 00:14:34.179 an idea, using up its value. That's a beautiful 00:14:34.179 --> 00:14:36.299 way to put it. It's acknowledging that ideas, 00:14:36.419 --> 00:14:39.179 rights, and brands are a form of fuel. You buy 00:14:39.179 --> 00:14:41.179 them, and then you burn them up over time to 00:14:41.179 --> 00:14:43.500 run your business. Amortization is the fuel gauge 00:14:43.500 --> 00:14:45.539 that tells you how much you have left. It really 00:14:45.539 --> 00:14:48.480 highlights again how time is the central character 00:14:48.480 --> 00:14:51.440 here. An asset is only an asset because of where 00:14:51.440 --> 00:14:53.620 it sits on the timeline. Its value is completely 00:14:53.620 --> 00:14:56.460 tied to its expiration date. The value is a function 00:14:56.460 --> 00:14:59.860 of time. Amortization is simply the math that 00:14:59.860 --> 00:15:02.000 links them together. Okay, speaking of rules 00:15:02.000 --> 00:15:05.120 and systematic manners, let's move to the entity 00:15:05.120 --> 00:15:08.259 that loves rules more than anyone else. Uh -oh. 00:15:08.320 --> 00:15:10.759 We are going to the government. We are talking 00:15:10.759 --> 00:15:13.639 tax law. Now, you might be thinking, wait, didn't 00:15:13.639 --> 00:15:16.580 we just do accounting? Isn't tax just a part 00:15:16.580 --> 00:15:18.539 of accounting? I definitely thought that. They 00:15:18.539 --> 00:15:20.600 seem like the same thing. But the source material 00:15:20.600 --> 00:15:23.519 for tax law gives a definition that is slightly, 00:15:23.620 --> 00:15:26.399 but very importantly, different. Let's hear it. 00:15:26.919 --> 00:15:29.600 Amortization, tax law, the cost recovery system 00:15:29.600 --> 00:15:33.399 for intangible property. Short, punchy, but the 00:15:33.399 --> 00:15:36.200 framing is completely different. It is. The accounting 00:15:36.200 --> 00:15:38.840 definition called it expensing. This definition 00:15:38.840 --> 00:15:41.600 calls it a cost recovery system. And words matter, 00:15:41.820 --> 00:15:45.269 especially in law. Expensing sounds like a negative. 00:15:45.389 --> 00:15:47.970 It sounds like losing value, a cost you have 00:15:47.970 --> 00:15:51.029 to eat. Cost recovery, on the other hand, sounds 00:15:51.029 --> 00:15:53.250 like a positive. It sounds like you are getting 00:15:53.250 --> 00:15:55.210 something back. Explain that. Who is getting 00:15:55.210 --> 00:15:58.549 what back? The taxpayer. The business owner. 00:15:58.830 --> 00:16:01.529 Put yourself back in their shoes. You just spent 00:16:01.529 --> 00:16:03.950 that $20 million on the patent. That cash is 00:16:03.950 --> 00:16:06.629 gone. It left your bank account. Right. It's 00:16:06.629 --> 00:16:09.409 a real cost I incurred. Now, when you file your 00:16:09.409 --> 00:16:11.990 taxes at the end of the year, you want to tell 00:16:11.990 --> 00:16:15.740 the IRS, hey, I spent $20 million. That's a legitimate 00:16:15.740 --> 00:16:17.820 business expense. I shouldn't have paid taxes 00:16:17.820 --> 00:16:19.740 on that money. You want to deduct it from your 00:16:19.740 --> 00:16:22.500 income? You want to deduct it now? You want the 00:16:22.500 --> 00:16:25.460 entire tax break today. You want that immediate 00:16:25.460 --> 00:16:28.179 gratification. But the government says no. The 00:16:28.179 --> 00:16:30.460 government says, whoa, whoa, slow down there. 00:16:30.830 --> 00:16:32.750 That patent is going to help you make money for 00:16:32.750 --> 00:16:35.210 the next 20 years. We are not going to let you 00:16:35.210 --> 00:16:37.769 take the entire tax deduction today for something 00:16:37.769 --> 00:16:40.129 that has a 20 -year benefit. So they force you 00:16:40.129 --> 00:16:42.309 to wait. They force you to amortize. They force 00:16:42.309 --> 00:16:44.350 you to use their cost recovery system. They say, 00:16:44.389 --> 00:16:46.470 we will allow you to recover the tax benefit 00:16:46.470 --> 00:16:48.929 of that cost, but we are going to control the 00:16:48.929 --> 00:16:50.950 speed. So you get a little bit of the deduction 00:16:50.950 --> 00:16:53.250 this year, a little bit next year, and so on 00:16:53.250 --> 00:16:56.179 for 20 years. Exactly. It's a control mechanism. 00:16:56.460 --> 00:16:59.580 It's a valve. It is a valve. The government controls 00:16:59.580 --> 00:17:02.279 the flow of tax deductions into the economy. 00:17:02.480 --> 00:17:05.019 And this is actually a really powerful economic 00:17:05.019 --> 00:17:07.940 tool for them. If the government wants to encourage 00:17:07.940 --> 00:17:11.619 businesses to invest in, say, research and development, 00:17:11.859 --> 00:17:14.779 they can change the amortization rules. Oh, really? 00:17:14.960 --> 00:17:17.819 How would that work? They could pass a law that 00:17:17.819 --> 00:17:20.960 says, hey, normally you have to amortize software 00:17:20.960 --> 00:17:23.480 development costs over five years. But for the 00:17:23.480 --> 00:17:25.819 next two years, as a special incentive, we'll 00:17:25.819 --> 00:17:27.539 let you do it in two years. That would make the 00:17:27.539 --> 00:17:30.460 tax break come much faster. Which creates a powerful 00:17:30.460 --> 00:17:32.380 incentive for companies to spend that money right 00:17:32.380 --> 00:17:35.779 now. So amortization, from the government's perspective, 00:17:36.039 --> 00:17:38.420 isn't just about accounting. It's a lever they 00:17:38.420 --> 00:17:41.150 can pull to steer the national economy. There 00:17:41.150 --> 00:17:43.230 is another word change here, too, that caught 00:17:43.230 --> 00:17:46.430 my eye. The accounting definition said intangible 00:17:46.430 --> 00:17:49.950 assets. The tax definition says intangible property. 00:17:50.210 --> 00:17:52.990 Good catch. Property feels heavier, doesn't it? 00:17:53.029 --> 00:17:55.910 It has a different weight. It feels more legal, 00:17:55.930 --> 00:17:59.829 more official. That's because it is. Asset is 00:17:59.829 --> 00:18:03.589 primarily an economic term. It's a store of value 00:18:03.589 --> 00:18:06.450 on a spreadsheet. Property is a legal term. It's 00:18:06.450 --> 00:18:08.960 a bundle of rights that you own. The right to 00:18:08.960 --> 00:18:11.619 exclude others from using your invention. Exactly. 00:18:11.619 --> 00:18:14.779 The tax code is law. So it views that patent 00:18:14.779 --> 00:18:17.859 not just as value on a balance sheet, but as 00:18:17.859 --> 00:18:20.160 a legal piece of property that you own with all 00:18:20.160 --> 00:18:22.119 the rights that come with it. The language reflects 00:18:22.119 --> 00:18:24.680 the perspective. So to synthesize this pillar, 00:18:24.920 --> 00:18:27.440 amortization and tax law is the government's 00:18:27.440 --> 00:18:29.759 way of saying we acknowledge you spent money 00:18:29.759 --> 00:18:32.720 and we will let you recover that cost through 00:18:32.720 --> 00:18:35.519 a tax deduction. But we decide the speed limit. 00:18:35.640 --> 00:18:37.859 It is the official speed limit on tax deductions 00:18:37.859 --> 00:18:40.920 for things you can't touch. Precisely. We have 00:18:40.920 --> 00:18:42.779 done the money stuff. We've killed the debt. 00:18:42.880 --> 00:18:44.660 We've expensed the asset. We've recovered the 00:18:44.660 --> 00:18:46.880 cost. Now we are going to do the hard pivot. 00:18:47.140 --> 00:18:49.200 This is the one that when I saw it in the source 00:18:49.200 --> 00:18:51.210 material, I honestly thought was a typo. The 00:18:51.210 --> 00:18:53.329 jump to the digital world. Computer science. 00:18:53.789 --> 00:18:56.809 Specifically, amortized analysis of algorithms. 00:18:57.210 --> 00:18:59.390 This is where the concept strips off his business 00:18:59.390 --> 00:19:01.710 suit, throws it in the corner, and puts on a 00:19:01.710 --> 00:19:03.869 hoodie. I mean, I didn't know algorithms had 00:19:03.869 --> 00:19:05.910 mortgages they needed to pay off. They don't 00:19:05.910 --> 00:19:08.569 have mortgages, but they absolutely do have costs. 00:19:08.809 --> 00:19:12.750 The source defines this as... Amortized analysis, 00:19:13.190 --> 00:19:16.690 a method of analyzing execution cost of algorithms. 00:19:17.029 --> 00:19:19.390 And we need to immediately redefine the word 00:19:19.390 --> 00:19:22.210 cost because the computer isn't spending dollars 00:19:22.210 --> 00:19:24.970 and cents when it runs a piece of code. So what 00:19:24.970 --> 00:19:27.910 is the currency here? What is it spending? Resources. 00:19:28.170 --> 00:19:30.910 Yeah. Pure and simple. Time is the big one. How 00:19:30.910 --> 00:19:33.190 many nanoseconds does this operation take? Memory 00:19:33.190 --> 00:19:35.549 is another. How many kilobytes of RAM do I need? 00:19:36.079 --> 00:19:38.059 And then there's electricity, processor cycles. 00:19:38.240 --> 00:19:40.079 Every time you click a button on your phone, 00:19:40.180 --> 00:19:42.259 every time you search for a file, the computer 00:19:42.259 --> 00:19:44.819 has to do work. That work is the execution cost. 00:19:45.059 --> 00:19:47.759 Okay, so some tasks are cheap. Super cheap. Adding 00:19:47.759 --> 00:19:49.960 one plus one, that's basically free for a modern 00:19:49.960 --> 00:19:52.599 computer. Moving a tiny bit of data from one 00:19:52.599 --> 00:19:54.900 place to another, also very cheap. And some are 00:19:54.900 --> 00:19:57.559 expensive. Very, very expensive. Imagine you're 00:19:57.559 --> 00:19:59.480 Google and you have to re -index a part of the 00:19:59.480 --> 00:20:01.680 internet. Or you're a bank and you need to sort 00:20:01.680 --> 00:20:03.980 a list of a billion transactions. Those are heavy 00:20:03.980 --> 00:20:06.799 lifts. They take real time and serious processing 00:20:06.799 --> 00:20:09.200 power. So where does the amortization come in? 00:20:09.299 --> 00:20:11.759 The definition says it's a method of analyzing 00:20:11.759 --> 00:20:15.440 this cost, not paying it, but analyzing it. This 00:20:15.440 --> 00:20:18.160 is the really cool part. Imagine you are writing 00:20:18.160 --> 00:20:21.099 a program. Let's use a really common example 00:20:21.099 --> 00:20:23.799 that computer science students learn about, something 00:20:23.799 --> 00:20:26.549 called a dynamic array. Basically, it's just 00:20:26.549 --> 00:20:28.769 a list that can grow. Okay. A list that grows. 00:20:29.009 --> 00:20:31.509 Simple enough. So you start by telling the computer, 00:20:31.690 --> 00:20:33.950 hey, give me a list that has room for four items. 00:20:34.069 --> 00:20:36.789 You add item one. That's super fast. Cheap. Item 00:20:36.789 --> 00:20:39.769 two, cheap. Item three, item four. All very, 00:20:39.869 --> 00:20:43.029 very fast operations. The cost is low. But now 00:20:43.029 --> 00:20:45.470 the list is full. Exactly. And now you want to 00:20:45.470 --> 00:20:47.829 add item five. The computer says, I have no room. 00:20:48.170 --> 00:20:50.930 So it has to do something drastic and very expensive. 00:20:51.109 --> 00:20:52.869 What does it do? It has to create a brand new 00:20:52.869 --> 00:20:56.009 list that is double the size. So eight slots. 00:20:56.450 --> 00:20:59.289 Then it has to painstakingly copy item one, item 00:20:59.289 --> 00:21:01.809 two, item three, and item four over to the new 00:21:01.809 --> 00:21:04.609 list. Then it deletes the old smaller list. And 00:21:04.609 --> 00:21:06.849 finally, after all that work, it adds your new 00:21:06.849 --> 00:21:09.450 item five. That sounds like a lot of work compared 00:21:09.450 --> 00:21:11.690 to just adding an item. It's a massive spike 00:21:11.690 --> 00:21:14.359 in cost. That one operation might take 100 times 00:21:14.359 --> 00:21:16.759 longer than all the other operations. Now, if 00:21:16.759 --> 00:21:19.700 you looked only at that one moment, that specific 00:21:19.700 --> 00:21:21.799 millisecond where the resizing happened, you'd 00:21:21.799 --> 00:21:24.339 say, wow, this algorithm is terrible. It's so 00:21:24.339 --> 00:21:26.390 slow. It's inefficient. But that wouldn't be 00:21:26.390 --> 00:21:28.670 fair, would it? Why not? Because it only happens 00:21:28.670 --> 00:21:30.990 once in a while. Once you resize to eight slots, 00:21:31.289 --> 00:21:33.170 the next few items, six, seven, eight, are all 00:21:33.170 --> 00:21:35.849 cheap again. You don't have to do that big expensive 00:21:35.849 --> 00:21:38.230 operation again until you want to add item nine. 00:21:38.509 --> 00:21:41.089 Exactly. You absolutely nailed it. Amortized 00:21:41.089 --> 00:21:43.869 analysis is the method of looking at that cost 00:21:43.869 --> 00:21:47.309 not as a single event, but over the whole sequence 00:21:47.309 --> 00:21:49.430 of operations. You average it out. You take that 00:21:49.430 --> 00:21:51.589 one big expensive spike and you mentally spread 00:21:51.589 --> 00:21:54.789 it out. You amortize it over all the cheap operations. 00:21:55.049 --> 00:21:57.660 that came before it Oh, I see. It's about smoothing 00:21:57.660 --> 00:21:59.660 out the curve. Can I use a household analogy? 00:21:59.880 --> 00:22:02.180 Oh, please do. It's like buying a Costco membership. 00:22:02.539 --> 00:22:04.900 I love the Costco analogy. Go on. The day you 00:22:04.900 --> 00:22:07.400 walk into Costco to sign up, it's a very expensive 00:22:07.400 --> 00:22:11.420 day. You have to pay, what, $60 or $120 right 00:22:11.420 --> 00:22:13.839 up front just to get the card. That is a high 00:22:13.839 --> 00:22:16.299 execution cost for that one specific shopping 00:22:16.299 --> 00:22:18.779 trip. A huge spike. If you only ever went to 00:22:18.779 --> 00:22:21.039 Costco once, that would be the most expensive 00:22:21.039 --> 00:22:23.539 hot dog in history. Right. But you don't go once. 00:22:23.619 --> 00:22:26.630 You go 50 times that year. And every other time 00:22:26.630 --> 00:22:29.289 you go, you just flash the card and walk in for 00:22:29.289 --> 00:22:31.930 free. Those are the cheap operations. So if you 00:22:31.930 --> 00:22:34.829 look at the year as a whole. The amortized cost 00:22:34.829 --> 00:22:36.970 of that membership is just a couple of dollars 00:22:36.970 --> 00:22:39.650 per trip. It becomes negligible when you spread 00:22:39.650 --> 00:22:42.029 it out. That is exactly what computer scientists 00:22:42.029 --> 00:22:44.930 do. They look at the worst case operation. They're 00:22:44.930 --> 00:22:47.750 resizing the membership fee. And they say, we 00:22:47.750 --> 00:22:50.849 can afford this expensive moment because we earned 00:22:50.849 --> 00:22:53.650 enough credit during all the cheap moments to 00:22:53.650 --> 00:22:56.019 pay for it. Earned enough credit. That sounds 00:22:56.019 --> 00:22:57.559 like banking again. It sounds like we're back 00:22:57.559 --> 00:23:00.779 at the loan. It is the exact same logic. In the 00:23:00.779 --> 00:23:04.420 loan, you make small monthly payments to slowly 00:23:04.420 --> 00:23:07.920 kill the big debt. In the algorithm, you do many 00:23:07.920 --> 00:23:12.380 cheap operations to pay for the one big expensive 00:23:12.380 --> 00:23:15.240 operation. So it's about perspective. It's about 00:23:15.240 --> 00:23:18.039 not getting fixated on the spike. It's about 00:23:18.039 --> 00:23:20.880 widening the lens. If you zoom in on that one 00:23:20.880 --> 00:23:23.160 spike, it looks like a disaster. If you zoom 00:23:23.160 --> 00:23:24.660 out and look at the whole timeline, it looks 00:23:24.660 --> 00:23:26.660 perfectly efficient and manageable. That connects 00:23:26.660 --> 00:23:28.579 right back to the life of the loan. You have 00:23:28.579 --> 00:23:31.160 to look at the whole life of the process to understand 00:23:31.160 --> 00:23:34.440 the true cost. Precisely. You can't judge the 00:23:34.440 --> 00:23:37.619 cost of an algorithm or mortgage based on a single 00:23:37.619 --> 00:23:39.839 snapshot in time. You have to watch the whole 00:23:39.839 --> 00:23:42.279 movie. That is wild. It's the same philosophy 00:23:42.279 --> 00:23:44.819 just applied to processor cycles instead of pennies. 00:23:44.960 --> 00:23:47.079 It's a universal way of understanding that expensive 00:23:47.079 --> 00:23:49.720 moments can be made manageable if they are supported 00:23:49.720 --> 00:23:52.160 by a long period of cheap moments that pay for 00:23:52.160 --> 00:23:55.039 them. Okay, we have one more stop on this roadmap. 00:23:55.359 --> 00:23:57.579 And this one might be the most surprising of 00:23:57.579 --> 00:23:59.680 all because it takes us out of the digital world, 00:23:59.779 --> 00:24:02.019 out of the bank, and onto the street. Literally 00:24:02.019 --> 00:24:05.299 onto the street. The physical world. Bricks and 00:24:05.299 --> 00:24:07.900 mortar. The source definition here is almost 00:24:07.900 --> 00:24:09.839 a short story. It's dramatic. Listen to this. 00:24:10.220 --> 00:24:14.640 Amortization, zoning. The time period a nonconforming 00:24:14.640 --> 00:24:17.720 property has to conform to a new zoning classification 00:24:17.720 --> 00:24:21.279 before the nonconforming use becomes prohibited. 00:24:21.680 --> 00:24:23.759 There is immediate conflict in that sentence. 00:24:23.980 --> 00:24:26.279 There is. It sounds like a legal thriller. You 00:24:26.279 --> 00:24:28.299 have a nonconforming property, you have a time 00:24:28.299 --> 00:24:31.559 period, and you have a threat. before the use 00:24:31.559 --> 00:24:33.859 becomes prohibited. Let's set the scene because 00:24:33.859 --> 00:24:36.119 this is the very real thing that happens in cities 00:24:36.119 --> 00:24:38.079 every single day. Let's say you own a business. 00:24:38.259 --> 00:24:40.500 It's an auto body shop. It's a little noisy. 00:24:40.579 --> 00:24:42.259 It smells like paint and oil. Okay. But you've 00:24:42.259 --> 00:24:44.420 been there for 20 years. When you first built 00:24:44.420 --> 00:24:46.839 it, the whole neighborhood was industrial. You 00:24:46.839 --> 00:24:48.759 followed all the rules at the time. You were 00:24:48.759 --> 00:24:51.400 a good business owner. Okay. I'm a law -abiding 00:24:51.400 --> 00:24:54.700 citizen. But cities change. They evolve. Over 00:24:54.700 --> 00:24:57.119 those 20 years, the city grew around you. People 00:24:57.119 --> 00:24:59.880 started moving in. Developers built nice condos. 00:24:59.920 --> 00:25:02.759 Hip coffee shops opened up. And suddenly, the 00:25:02.759 --> 00:25:05.000 city council decides to change the zoning map. 00:25:05.220 --> 00:25:08.140 They say, this neighborhood is now officially 00:25:08.140 --> 00:25:11.380 residential. No more factories. No more auto 00:25:11.380 --> 00:25:14.380 shops. So my shop is now. What did the definition 00:25:14.380 --> 00:25:17.740 say? Nonconforming. Right. You don't fit the 00:25:17.740 --> 00:25:20.880 rules anymore. You are a square peg in a newly 00:25:20.880 --> 00:25:24.170 round hole. Now, here is the dilemma for the 00:25:24.170 --> 00:25:26.670 city. They want you gone. They want you gone. 00:25:26.829 --> 00:25:29.589 They want the neighborhood to be quiet and nice 00:25:29.589 --> 00:25:32.069 for the new residents. But you own that building. 00:25:32.170 --> 00:25:34.390 You built that business from the ground up. They 00:25:34.390 --> 00:25:36.009 can't just kick me out, can they? That seems 00:25:36.009 --> 00:25:38.769 unconstitutional. Taking my property. Well, they 00:25:38.769 --> 00:25:40.769 can't just seize your property without paying 00:25:40.769 --> 00:25:42.950 you for it. That's called eminent domain, and 00:25:42.950 --> 00:25:45.170 it's very expensive for the city. And they can't 00:25:45.170 --> 00:25:48.170 just say, you must shut down today without causing 00:25:48.170 --> 00:25:50.779 a massive lawsuit. So they invented a clever 00:25:50.779 --> 00:25:53.380 workaround. They invented amortization. And in 00:25:53.380 --> 00:25:55.420 this context, the definition says amortization 00:25:55.420 --> 00:25:58.579 is the time period. Yes. This is the most direct 00:25:58.579 --> 00:26:01.779 link yet. In a loan, amortization was a process 00:26:01.779 --> 00:26:04.960 of paying money. Here, amortization is literally 00:26:04.960 --> 00:26:07.980 a period of time. The city says to you, the auto 00:26:07.980 --> 00:26:10.519 shop owner, we are not shutting you down today. 00:26:10.660 --> 00:26:13.160 We are going to give you an amortization period, 00:26:13.400 --> 00:26:15.640 let's say five years. It's a countdown clock. 00:26:15.880 --> 00:26:18.059 It's a grace period. The city's legal argument 00:26:18.059 --> 00:26:21.859 is this. Over those five years, you can continue 00:26:21.859 --> 00:26:24.519 to run your shop. You can make your profit. You 00:26:24.519 --> 00:26:26.880 can recoup your investment in the building. In 00:26:26.880 --> 00:26:29.039 other words, you get the last bit of economic 00:26:29.039 --> 00:26:31.619 value out of it. And what happens when the five 00:26:31.619 --> 00:26:34.539 years are up? The source is brutal and final 00:26:34.539 --> 00:26:37.980 here, before the non -conforming use becomes 00:26:37.980 --> 00:26:41.920 prohibited. So, game over. Game over. The city 00:26:41.920 --> 00:26:44.960 can come and legally force you to stop operating 00:26:44.960 --> 00:26:47.319 as an auto shop. You still own the land. You 00:26:47.319 --> 00:26:50.180 still own the bricks. But the right to fix cars 00:26:50.180 --> 00:26:54.160 there is extinguished. It's dead. That feels 00:26:54.160 --> 00:26:57.880 incredibly harsh. It is by far the most aggressive 00:26:57.880 --> 00:27:00.559 definition of amortization we've looked at. It's 00:27:00.559 --> 00:27:03.119 legally controversial in many places. But look 00:27:03.119 --> 00:27:04.700 at the parallel to the loan again. It's stunning. 00:27:04.859 --> 00:27:06.980 What's the parallel? In a loan, you are killing 00:27:06.980 --> 00:27:10.849 the debt over a period of time. In zoning? You 00:27:10.849 --> 00:27:12.630 are killing the legal use of the building over 00:27:12.630 --> 00:27:14.789 a period of time. You are extinguishing a right. 00:27:15.170 --> 00:27:18.269 Exactly. The right to run that shop is being 00:27:18.269 --> 00:27:21.589 slowly amortized, killed off over a set schedule, 00:27:21.690 --> 00:27:24.109 just like your mortgage principle. But I guess 00:27:24.109 --> 00:27:26.049 from the city planner's perspective, it's a way 00:27:26.049 --> 00:27:28.369 to be fair. That's the argument. It's the buffer. 00:27:28.509 --> 00:27:30.450 It's the shock absorber. If they shut you down 00:27:30.450 --> 00:27:33.349 instantly, that's a huge spike, just like in 00:27:33.349 --> 00:27:35.230 the algorithm. It's a disaster for the business 00:27:35.230 --> 00:27:38.259 owner. Right. By giving them five years, they 00:27:38.259 --> 00:27:40.799 smooth out that spike. They turn the immediate 00:27:40.799 --> 00:27:43.059 eviction into a manageable transition. It gives 00:27:43.059 --> 00:27:45.259 you time to plan, time to find a new location, 00:27:45.539 --> 00:27:47.900 time to adjust your business model. Exactly. 00:27:48.359 --> 00:27:51.950 It's the shock absorber of urban planning. It 00:27:51.950 --> 00:27:54.670 attempts to balance the public desire for a nicer 00:27:54.670 --> 00:27:57.230 neighborhood with the private property rights 00:27:57.230 --> 00:28:00.170 of the existing business owner. Wow. Okay. We 00:28:00.170 --> 00:28:02.650 have covered a massive amount of ground. We've 00:28:02.650 --> 00:28:04.910 been to the bank, the accountant's office, the 00:28:04.910 --> 00:28:07.490 tax bureau, the server room, and the city council 00:28:07.490 --> 00:28:09.549 planning meeting. It's been a whirlwind tour. 00:28:09.730 --> 00:28:11.869 So now we need to do the hard work. We need to 00:28:11.869 --> 00:28:14.170 synthesize this. We promised at the top that 00:28:14.170 --> 00:28:16.730 we would find the pattern in the noise. Let's 00:28:16.730 --> 00:28:18.470 lay the five pillars out on the table. Let's 00:28:18.470 --> 00:28:20.690 look at them side by side. Okay. Pillar one. 00:28:21.200 --> 00:28:24.079 The loan. It's about decreasing principle over 00:28:24.079 --> 00:28:27.000 the life of the loan. Pillar two, accounting. 00:28:27.420 --> 00:28:30.359 It's the systematic expensing of intangible assets. 00:28:30.680 --> 00:28:34.000 Pillar three, tax law. A cost recovery system 00:28:34.000 --> 00:28:37.220 for intangible property. Pillar four, algorithms. 00:28:37.660 --> 00:28:40.759 A method for analyzing execution cost over time. 00:28:40.960 --> 00:28:44.099 And pillar five, zoning. The time period you 00:28:44.099 --> 00:28:46.440 get to conform before your use is prohibited. 00:28:46.940 --> 00:28:49.019 When you lay them out like that, the common thread 00:28:49.019 --> 00:28:51.339 becomes almost blindingly obvious. What do you 00:28:51.339 --> 00:28:54.240 see? I see two words, time and transition. Expand 00:28:54.240 --> 00:28:56.240 on that. In every single one of these definitions, 00:28:56.460 --> 00:28:59.500 amortization is the mechanism humans invented 00:28:59.500 --> 00:29:01.940 to handle a transition from state A to state 00:29:01.940 --> 00:29:04.660 B. And usually state A and state B are very, 00:29:04.700 --> 00:29:06.660 very far apart. Okay, let's test that theory. 00:29:07.160 --> 00:29:10.559 In the loan, state A is... I have a massive crushing 00:29:10.559 --> 00:29:13.160 debt I can't possibly pay today. And state B 00:29:13.160 --> 00:29:16.500 is I own my home free and clear. You can't jump 00:29:16.500 --> 00:29:18.660 that gap instantly. It's too wide. You need a 00:29:18.660 --> 00:29:21.420 bridge. Amortization is the bridge. 30 years 00:29:21.420 --> 00:29:24.140 of payments month by month. In accounting, state 00:29:24.140 --> 00:29:27.240 A is I just spent a fortune on this idea, this 00:29:27.240 --> 00:29:30.359 patent. State B is I've used up all the economic 00:29:30.359 --> 00:29:33.779 value of that idea. And amortization is the systematic 00:29:33.779 --> 00:29:36.640 path between them. It's the slow walk from full 00:29:36.640 --> 00:29:40.720 value to zero. In algorithms, state A is a high 00:29:40.720 --> 00:29:42.700 computation spike happens. Everything grinds 00:29:42.700 --> 00:29:46.640 to a halt. State B is the average performance 00:29:46.640 --> 00:29:49.740 is smooth and manageable. The amortized analysis 00:29:49.740 --> 00:29:52.299 is what connects those two realities. And in 00:29:52.299 --> 00:29:56.380 zoning, state A is noncompliance. The wrong building 00:29:56.380 --> 00:29:59.359 is in the wrong place. State B is full compliance, 00:29:59.519 --> 00:30:02.819 a nice, quiet residential neighborhood. The amortization 00:30:02.819 --> 00:30:06.319 period is the bridge from the old reality to 00:30:06.319 --> 00:30:08.410 the new one. So it is the buffer. It is the buffer. 00:30:08.529 --> 00:30:11.130 It is the shock absorber of reality. Think about 00:30:11.130 --> 00:30:12.849 it. Most big changes, whether they're financial, 00:30:13.049 --> 00:30:15.349 physical, or computational, are just too big 00:30:15.349 --> 00:30:17.390 to handle all at once. We need a break. We would. 00:30:17.430 --> 00:30:19.109 The system would break. You can't pay the house 00:30:19.109 --> 00:30:21.410 off in a day. You can't resize the database every 00:30:21.410 --> 00:30:23.569 single second. You can't shut down the factory 00:30:23.569 --> 00:30:26.289 instantly without causing chaos. We aren't infinite. 00:30:26.410 --> 00:30:29.049 We have limits. Exactly. We have limited cash. 00:30:29.190 --> 00:30:31.170 We have limited processing power. We have a limited 00:30:31.170 --> 00:30:33.950 tolerance for disruption. Amortization is the 00:30:33.950 --> 00:30:36.920 brilliant tool we invented. Spread that pain 00:30:36.920 --> 00:30:40.779 or that cost or that change across time to make 00:30:40.779 --> 00:30:43.019 it bearable. It makes the impossible manageable. 00:30:43.420 --> 00:30:45.920 That is the perfect summary. It breaks the big 00:30:45.920 --> 00:30:47.920 scary thing down into little bite -sized pieces 00:30:47.920 --> 00:30:50.539 that we can deal with day by day, month by month, 00:30:50.619 --> 00:30:54.900 year by year. That is actually strangely comforting. 00:30:55.160 --> 00:30:57.839 It is, isn't it? We started this deep dive thinking 00:30:57.839 --> 00:31:00.920 amortization was this boring, scary, technical 00:31:00.920 --> 00:31:04.579 word. But actually... It's kind of a hero. A 00:31:04.579 --> 00:31:07.140 quiet hero. It's the thing that lets us buy homes. 00:31:07.319 --> 00:31:09.420 It's the thing that lets businesses invest in 00:31:09.420 --> 00:31:12.180 big ideas. It's the thing that makes our software 00:31:12.180 --> 00:31:15.279 run smoothly without us even noticing. It's the 00:31:15.279 --> 00:31:17.619 thing that lets our cities evolve without destroying 00:31:17.619 --> 00:31:19.779 people's livelihoods overnight. It's the structure 00:31:19.779 --> 00:31:22.400 of patience. The structure of patience. I like 00:31:22.400 --> 00:31:24.299 that a lot. It's applying a logical timeline 00:31:24.299 --> 00:31:26.519 to a problem so that the problem can actually 00:31:26.519 --> 00:31:29.319 be solved. without causing a catastrophe. So 00:31:29.319 --> 00:31:32.559 we've gone from a scary financial term to the 00:31:32.559 --> 00:31:35.200 structure of patience. That is quite a journey. 00:31:35.380 --> 00:31:37.440 It's what happens when you stop and really look 00:31:37.440 --> 00:31:39.700 at the words. Before we go, I want to leave our 00:31:39.700 --> 00:31:42.380 listener with one final provocative thought to 00:31:42.380 --> 00:31:45.660 chew on. We talked about how in zoning, amortization 00:31:45.660 --> 00:31:50.240 is a countdown to a prohibition and ending. And 00:31:50.240 --> 00:31:53.920 in a loan, it's a countdown to the death of the 00:31:53.920 --> 00:31:56.940 debt. Another ending. Yes. So here's a thought. 00:31:57.220 --> 00:32:00.599 Is amortization actually just a fancy word for 00:32:00.599 --> 00:32:04.339 a slow scheduled ending? Ooh, that's good. Think 00:32:04.339 --> 00:32:07.019 about it. In every single case, it's managing 00:32:07.019 --> 00:32:09.519 the process of something coming to an end, whether 00:32:09.519 --> 00:32:11.119 it's the ending of a debt, the ending of the 00:32:11.119 --> 00:32:13.259 value of an asset, or the ending of the legal 00:32:13.259 --> 00:32:15.839 use of a building. It's not just a process of 00:32:15.839 --> 00:32:18.480 payment. It's a process of ending something methodically. 00:32:18.700 --> 00:32:20.920 That is a profound way to look at it. It's the 00:32:20.920 --> 00:32:23.380 art of the long goodbye. The art of the long 00:32:23.380 --> 00:32:26.180 goodbye. I love that. Whether you are saying 00:32:26.180 --> 00:32:29.140 goodbye to your mortgage or goodbye to that old 00:32:29.140 --> 00:32:30.859 factory in the neighborhood that doesn't fit 00:32:30.859 --> 00:32:33.900 anymore, it forces you to confront the timeline. 00:32:34.019 --> 00:32:37.579 It says, this is finite, this will end, and here 00:32:37.579 --> 00:32:41.180 is the exact schedule. So, listener, that is 00:32:41.180 --> 00:32:43.599 your homework. I want you to look around your 00:32:43.599 --> 00:32:46.200 life. Where do you see amortization? And I don't 00:32:46.200 --> 00:32:48.039 just mean on your bank statement. No, look deeper. 00:32:48.200 --> 00:32:51.039 Where are you paying down a cost? Maybe it's 00:32:51.039 --> 00:32:52.960 an emotional cost. Maybe it's a physical one. 00:32:53.039 --> 00:32:54.859 Maybe it's a big project you're working on over 00:32:54.859 --> 00:32:58.740 time. Where in your life are you in the middle 00:32:58.740 --> 00:33:02.440 of a slow scheduled ending? And are you following 00:33:02.440 --> 00:33:04.759 the schedule? That's the real question. Because 00:33:04.759 --> 00:33:07.650 if you aren't amortizing. You're just treading 00:33:07.650 --> 00:33:09.750 water. And the interest is piling up. Exactly. 00:33:10.069 --> 00:33:12.029 Thanks for diving deep with us today. It's been 00:33:12.029 --> 00:33:13.009 a pleasure. See you next time.
