WEBVTT 00:00:00.000 --> 00:00:03.459 So imagine reaching into your pocket right now. 00:00:03.580 --> 00:00:05.660 Yeah, just fishing around in there. Right. You 00:00:05.660 --> 00:00:08.400 fish around, pass your keys, and you pull out 00:00:08.400 --> 00:00:11.900 a $5 bill. You look down at it and. Well, what 00:00:11.900 --> 00:00:13.679 are you actually holding? I mean, to most people, 00:00:13.759 --> 00:00:15.939 it feels like a universal constant. Exactly. 00:00:16.140 --> 00:00:18.820 It's this specific blend of cotton and linen, 00:00:19.339 --> 00:00:21.920 a familiar color, just a number you've recognized 00:00:21.920 --> 00:00:24.000 since you were a little kid. Right. It's clean, 00:00:24.300 --> 00:00:26.879 it's static, and it's completely straightforward. 00:00:27.079 --> 00:00:29.460 You know, buys you a quick coffee, maybe a snack 00:00:29.460 --> 00:00:32.060 from a vending machine. But depending entirely 00:00:32.060 --> 00:00:34.200 on where you happen to be standing on the planet 00:00:34.200 --> 00:00:36.780 at this very second, you might not be holding 00:00:36.780 --> 00:00:39.359 paper or cotton at all. Oh, for sure. You might 00:00:39.359 --> 00:00:42.659 be holding like a heavy metal coin or maybe a 00:00:42.659 --> 00:00:45.560 piece of sleek transparent polymer. And that 00:00:45.560 --> 00:00:48.520 illusion of the static universally understood 00:00:48.520 --> 00:00:51.880 five is exactly what we are tearing down today. 00:00:53.240 --> 00:00:55.340 Welcome to the deep dive. We've got a really 00:00:55.340 --> 00:00:58.380 fascinating set of sources today. We do. We're 00:00:58.380 --> 00:01:00.240 taking a look at a stack of sources you shared 00:01:00.240 --> 00:01:02.759 with us and the core of it is actually deceptively 00:01:02.759 --> 00:01:06.709 simple. Our mission today is diving into a single 00:01:06.709 --> 00:01:10.409 Wikipedia disambiguation page for the term $5. 00:01:10.849 --> 00:01:13.109 Literally just a dollar sign and the number five. 00:01:13.150 --> 00:01:15.590 Right. But we're going to show you how this one 00:01:15.590 --> 00:01:18.510 specific number acts as a secret decoder ring 00:01:18.510 --> 00:01:23.189 for global trade, human psychology, and even 00:01:23.189 --> 00:01:25.609 pop culture. And you know, the very fact that 00:01:25.609 --> 00:01:28.810 a disambiguation page exists for this term at 00:01:28.810 --> 00:01:32.090 all is your first major clue that we are dealing 00:01:32.090 --> 00:01:33.870 with something massive here. Yeah, because we 00:01:33.870 --> 00:01:36.069 only use those pages when things get complicated. 00:01:36.670 --> 00:01:39.189 Exactly. Wikipedia uses disambiguation pages 00:01:39.189 --> 00:01:41.590 when human beings have taken a single simple 00:01:41.590 --> 00:01:44.670 concept and applied it in dozens of overlapping, 00:01:45.010 --> 00:01:47.650 highly localized, and sometimes really conflicting 00:01:47.650 --> 00:01:49.950 ways across the globe. Okay, let's unpack this. 00:01:50.109 --> 00:01:52.569 Think of the $5 denomination like the universal 00:01:52.569 --> 00:01:54.730 blood type of currency. Oh, I like that. Right. 00:01:54.890 --> 00:01:56.170 It shows up absolutely everywhere around the 00:01:56.170 --> 00:01:57.950 world. It is universally mathematically accepted, 00:01:58.409 --> 00:02:00.730 but it adapts to look entirely different depending 00:02:00.730 --> 00:02:03.489 on the specific economic body it lives inside. 00:02:03.870 --> 00:02:06.189 Yeah, that's a perfect way to put it. It's less 00:02:06.189 --> 00:02:09.500 of a static object and more like water. It perfectly 00:02:09.500 --> 00:02:11.939 takes the shape of whatever economic glass you 00:02:11.939 --> 00:02:14.400 pour it into. That is a fantastic visual and 00:02:14.400 --> 00:02:16.759 it really sets the stakes perfectly because before 00:02:16.759 --> 00:02:19.180 we can travel the globe looking at every single 00:02:19.180 --> 00:02:22.219 variation of the specific blood type we have 00:02:22.219 --> 00:02:24.319 to, you know, establish the baseline. We've got 00:02:24.319 --> 00:02:25.900 to look at the heavy hitters. Right, we need 00:02:25.900 --> 00:02:28.099 to look at those heavy hitters and the fundamental 00:02:28.099 --> 00:02:30.780 physical formats this currency actually takes. 00:02:30.879 --> 00:02:33.120 Because if someone says five dollar note to you 00:02:33.289 --> 00:02:36.830 Your brain immediately defaults to the currency 00:02:36.830 --> 00:02:39.289 of your own country. Of course it does. And the 00:02:39.289 --> 00:02:41.490 source material immediately points us to the 00:02:41.490 --> 00:02:44.229 major English -speaking economies that use a 00:02:44.229 --> 00:02:47.580 $5 note. We're talking about the United States, 00:02:48.240 --> 00:02:50.300 Australia, Canada, and New Zealand. And these 00:02:50.300 --> 00:02:54.599 represent massive, highly complex, totally distinct 00:02:54.599 --> 00:02:58.159 economies. Yet, they all anchor a significant 00:02:58.159 --> 00:03:01.259 portion of their physical daily cash flow on 00:03:01.259 --> 00:03:04.219 this exact same structural unit. They established 00:03:04.219 --> 00:03:07.830 the five as a true global heavy hitter. But then, 00:03:08.030 --> 00:03:10.509 right at the top of the source material, we get 00:03:10.509 --> 00:03:13.530 hit with this fascinating anomaly that completely 00:03:13.530 --> 00:03:16.030 disrupts that baseline. Hong Kong? Yes, Hong 00:03:16.030 --> 00:03:18.689 Kong. According to the source, the Hong Kong 00:03:18.689 --> 00:03:22.449 economy issues a $5 note, but it also issues 00:03:22.449 --> 00:03:26.710 a $5 coin at the exact same time. The dual format. 00:03:27.030 --> 00:03:30.129 It is incredibly rare to see both actively supported 00:03:30.129 --> 00:03:33.150 in a modern advanced economy. See, I have to 00:03:33.150 --> 00:03:35.599 push back on this because logically, This makes 00:03:35.599 --> 00:03:38.719 zero sense to me. Oh, so? Why would an entire 00:03:38.719 --> 00:03:41.930 economy spend the money to support two entirely 00:03:41.930 --> 00:03:44.330 different physical formats for the exact same 00:03:44.330 --> 00:03:46.830 value. It feels completely redundant. It does 00:03:46.830 --> 00:03:48.830 seem that way on the surface. I mean, it's like 00:03:48.830 --> 00:03:51.370 having both a physical metal key and a digital 00:03:51.370 --> 00:03:53.550 keypad open the exact same front door of your 00:03:53.550 --> 00:03:56.229 house. Doesn't that cause massive logistical 00:03:56.229 --> 00:03:59.669 confusion for cash registers or banks or just 00:03:59.669 --> 00:04:01.669 everyday people trying to organize their wallets? 00:04:01.770 --> 00:04:04.050 What's fascinating here is that duality actually 00:04:04.050 --> 00:04:07.030 represents a highly specific transitional state 00:04:07.030 --> 00:04:10.199 in an economy's physical cash usage. It seems 00:04:10.199 --> 00:04:12.939 redundant on paper, but it caters to entirely 00:04:12.939 --> 00:04:15.800 different types of everyday human behavior and 00:04:15.800 --> 00:04:18.240 what economists call transaction velocities. 00:04:18.459 --> 00:04:20.680 Wait, transaction velocities. Break that down 00:04:20.680 --> 00:04:23.360 for me. How does velocity dictate whether money 00:04:23.360 --> 00:04:26.620 is made of paper or metal? So it comes down to 00:04:26.620 --> 00:04:29.399 the physical lifespan of the money and how fast 00:04:29.399 --> 00:04:32.899 it changes hands. Think about high velocity. 00:04:33.209 --> 00:04:35.949 rapid exchange environments. Like what? We're 00:04:35.949 --> 00:04:38.649 talking about transit systems, subway turnstiles, 00:04:38.949 --> 00:04:41.689 busy street markets, vending machines. In those 00:04:41.689 --> 00:04:43.889 environments, money takes an absolute beating. 00:04:44.050 --> 00:04:45.850 Oh right, because people are just shoving it 00:04:45.850 --> 00:04:48.529 into machines and pockets. Exactly. Paper or 00:04:48.529 --> 00:04:51.750 even polymer notes degrade. They tear, they get 00:04:51.750 --> 00:04:54.850 crumpled, they get wet. If a specific denomination, 00:04:54.990 --> 00:04:57.790 like the five, is the primary unit used for these 00:04:57.790 --> 00:05:00.149 rapid daily transactions, the central bank has 00:05:00.149 --> 00:05:02.389 to constantly print replacement notes. Which 00:05:02.389 --> 00:05:04.709 I imagine gets expensive. Incredibly expensive. 00:05:04.829 --> 00:05:06.850 You're saying a country will actually spend the 00:05:06.850 --> 00:05:09.730 money to mint a heavy metal coin just because 00:05:09.730 --> 00:05:11.610 printing paper five becomes too expensive in 00:05:11.610 --> 00:05:14.310 the long run. Very much, yeah. But minting metal 00:05:14.310 --> 00:05:17.569 has to be a massive upfront cost. Oh, it is a 00:05:17.569 --> 00:05:21.579 huge upfront cost. But a coin is practically 00:05:21.579 --> 00:05:24.100 indestructible. It can circulate for decades 00:05:24.100 --> 00:05:27.600 without degrading. Wow, decades. Yeah. Meanwhile, 00:05:28.000 --> 00:05:31.480 a heavily used $5 paper note might only last 00:05:31.480 --> 00:05:34.300 like... Six to eight months in a busy city before 00:05:34.300 --> 00:05:37.139 it has to be shredded and replaced only six months 00:05:37.139 --> 00:05:39.600 Yeah, the long -term math heavily favors the 00:05:39.600 --> 00:05:41.879 coin for these high -velocity transit and market 00:05:41.879 --> 00:05:44.660 transactions Okay, that covers the coin. But 00:05:44.660 --> 00:05:46.740 then why keep the paper note at all? Why not 00:05:46.740 --> 00:05:49.120 just force everyone to use the coin and save 00:05:49.120 --> 00:05:51.759 the government? millions in printing costs. Because 00:05:51.759 --> 00:05:54.480 of the wallet. The wallet. People demand physical 00:05:54.480 --> 00:05:57.060 comfort. Nobody wants their pocket weighing three 00:05:57.060 --> 00:05:58.759 pounds because they got a bunch of heavy metal 00:05:58.759 --> 00:06:01.060 fives and change at the grocery store. Oh, yeah, 00:06:01.139 --> 00:06:03.120 that would be incredibly annoying. Consumers 00:06:03.120 --> 00:06:05.699 inherently prefer paper or lightweight polymer 00:06:05.699 --> 00:06:08.860 for bolt carrying. So an economy like Hong Kong 00:06:08.860 --> 00:06:12.540 basically compromises. I see. The system demands 00:06:12.540 --> 00:06:14.839 the durability of the coin for rapid transit, 00:06:14.899 --> 00:06:17.500 but the consumer demands the lightweight note 00:06:17.500 --> 00:06:20.259 for personal carrying. So it's a physical reaction 00:06:20.259 --> 00:06:23.040 to how human beings actually move through a city. 00:06:23.259 --> 00:06:26.180 Exactly. The format isn't arbitrary at all. It's 00:06:26.180 --> 00:06:28.399 literally a tug of war between durability and 00:06:28.399 --> 00:06:31.079 comfort. Yes. Okay. So we've established the 00:06:31.079 --> 00:06:33.480 heavyweights and we've seen this format war between 00:06:33.480 --> 00:06:37.240 coins and notes. But seeing the $5 unit exist 00:06:37.240 --> 00:06:40.420 in these major economies naturally begs a question. 00:06:40.980 --> 00:06:44.250 How far does the term dollar actually stretch 00:06:44.250 --> 00:06:47.350 when we attach it to this specific number. Far 00:06:47.350 --> 00:06:49.810 beyond North America and Australia, that's for 00:06:49.810 --> 00:06:52.709 sure. Yeah. The sheer volume of economies utilizing 00:06:52.709 --> 00:06:55.470 the term dollar attached to a five unit note 00:06:55.470 --> 00:06:58.750 or coin is staggering. It really is. I was looking 00:06:58.750 --> 00:07:00.730 through the source list and we are going on a 00:07:00.730 --> 00:07:02.569 global world tour here. We aren't just going 00:07:02.569 --> 00:07:04.490 to read the whole list, but we have to group 00:07:04.490 --> 00:07:06.670 some of these just to understand the scale. Let's 00:07:06.670 --> 00:07:09.430 do it. So you have major Caribbean financial 00:07:09.430 --> 00:07:11.790 hubs like the Bahamian dollar, the Barbadian 00:07:11.790 --> 00:07:14.019 dollar, the The Burmese dollar. The Burmese dollar. 00:07:14.360 --> 00:07:14.779 The Burmese dollar. The Burmese dollar. The Burmese 00:07:14.779 --> 00:07:14.779 dollar. The Burmese dollar. The Burmese dollar. 00:07:14.779 --> 00:07:14.920 The Burmese dollar. The Burmese dollar. The Burmese 00:07:14.920 --> 00:07:15.079 dollar. The Burmese dollar. The Burmese dollar. 00:07:15.079 --> 00:07:28.800 The Burmese dollar. The Burmese dollar. The Burmese 00:07:28.800 --> 00:07:31.480 dollar. I mean, I am honestly a little overwhelmed 00:07:31.480 --> 00:07:34.180 by the sheer geographical spread here. You have 00:07:34.180 --> 00:07:36.379 independent nations from the Caribbean to the 00:07:36.379 --> 00:07:38.660 Pacific Islands all the way to Africa. It's a 00:07:38.660 --> 00:07:41.699 massive footprint. Doesn't this dilute the very 00:07:41.699 --> 00:07:44.420 concept of what a dollar is? I mean, it feels 00:07:44.420 --> 00:07:47.079 less like a specific national currency and more 00:07:47.079 --> 00:07:49.399 like an open source franchise model for money. 00:07:49.500 --> 00:07:51.779 A franchise model. Yeah, like any country could 00:07:51.779 --> 00:07:54.439 just download the dollar operating system, tweak 00:07:54.439 --> 00:07:57.379 the logo and hit print. If we connect this to 00:07:57.379 --> 00:08:01.459 the bigger picture, this Dollar diaspora, as 00:08:01.459 --> 00:08:04.480 you could call it, perfectly highlights the globalization 00:08:04.480 --> 00:08:07.759 of financial terminology. Right. The word dollar 00:08:07.759 --> 00:08:10.259 has essentially become a linguistic shorthand 00:08:10.259 --> 00:08:12.860 for a standardized unit of trade. But the word 00:08:12.860 --> 00:08:14.759 isn't the most important part of that equation, 00:08:14.800 --> 00:08:18.139 is it? No, not at all. The critical element is 00:08:18.139 --> 00:08:19.939 the number five attached to it. Because of the 00:08:19.939 --> 00:08:23.009 math. Exactly. Look at the contrast in that list 00:08:23.009 --> 00:08:25.509 we just read. You have the Cayman Islands, which 00:08:25.509 --> 00:08:28.709 is a massive offshore financial hub, dealing 00:08:28.709 --> 00:08:31.189 in global wealth. And then you have the Solomon 00:08:31.189 --> 00:08:34.149 Islands, an economy heavily reliant on local 00:08:34.149 --> 00:08:37.830 agriculture and timber. These are vastly different 00:08:37.830 --> 00:08:39.870 economies with entirely different industries, 00:08:40.169 --> 00:08:42.330 populations, and scale. Right, they basically 00:08:42.330 --> 00:08:44.940 have nothing in common. Yet they both rely on 00:08:44.940 --> 00:08:47.639 the five as a key structural pillar of their 00:08:47.639 --> 00:08:51.419 cash system. This points to a universal mathematical 00:08:51.419 --> 00:08:54.259 sweet spot for human trade. Well, we count in 00:08:54.259 --> 00:08:56.700 a base 10 system, largely because we have 10 00:08:56.700 --> 00:08:59.480 fingers. So a unit of one is your baseline and 00:08:59.480 --> 00:09:02.139 a unit of 10 is your next major psychological 00:09:02.139 --> 00:09:06.120 tier. Exactly. The five is the perfect, indispensable 00:09:06.120 --> 00:09:08.820 bridge between them. It is all about cognitive 00:09:08.820 --> 00:09:11.559 ease and reducing the physical friction of trade. 00:09:11.960 --> 00:09:13.960 Let's actually visualize that friction for a 00:09:13.960 --> 00:09:16.399 second. Imagine we are running a market stall 00:09:16.399 --> 00:09:18.559 in one of these countries, but our government 00:09:18.559 --> 00:09:21.399 decided to, I don't know, just skip the five. 00:09:21.620 --> 00:09:24.440 They only gave us ones and tens. If I'm buying 00:09:24.440 --> 00:09:28.039 an $8 item, the physical act of making change 00:09:28.039 --> 00:09:30.580 becomes... nightmare. Precisely. If you hand 00:09:30.580 --> 00:09:32.559 me a ten, I have to count out and hand you back 00:09:32.559 --> 00:09:35.220 two individual ones. If you are paying with exact 00:09:35.220 --> 00:09:37.799 change, you have to hand me eight individual 00:09:37.799 --> 00:09:40.639 one dollar bills. That is incredibly inefficient. 00:09:40.940 --> 00:09:42.820 It slows down the line at the register. It slows 00:09:42.820 --> 00:09:44.720 down the line, it increases the chance of accounting 00:09:44.720 --> 00:09:47.960 error, and it creates a massive physical burden 00:09:47.960 --> 00:09:50.759 of paper. What if a country tried to use a different 00:09:50.759 --> 00:09:55.559 bridge, like Instead of a 1 -5 -10 system, what 00:09:55.559 --> 00:09:58.659 if they used a 1 -3 -7 system? That completely 00:09:58.659 --> 00:10:01.200 breaks the cognitive ease. Human working memory 00:10:01.200 --> 00:10:05.539 loves simple division. The 5 perfectly halves 00:10:05.539 --> 00:10:09.159 the 10. It requires zero mental load to calculate. 00:10:09.470 --> 00:10:13.110 If you have a $3 bill and a $7 bill, making change 00:10:13.110 --> 00:10:16.309 for a $9 item becomes a math puzzle every single 00:10:16.309 --> 00:10:23.250 time. And that mental friction physically slows 00:10:23.250 --> 00:10:26.129 down an economy. Removing friction stimulates 00:10:26.129 --> 00:10:29.039 trade. The human brain and the mathematics of 00:10:29.039 --> 00:10:31.240 efficient exchange demand a denomination that 00:10:31.240 --> 00:10:34.659 perfectly halves the base 10 tier. So it's hardwired 00:10:34.659 --> 00:10:38.179 into us. It is. So it doesn't matter if you are 00:10:38.179 --> 00:10:41.000 trading international stocks in Singapore or 00:10:41.000 --> 00:10:44.480 buying fruit in the Bahamas. The five -unit denomination 00:10:44.480 --> 00:10:47.639 is an absolute economic inevitability. Here's 00:10:47.639 --> 00:10:50.440 where it gets really interesting. Because if 00:10:50.440 --> 00:10:53.340 the math is an inevitability, what happens when 00:10:53.340 --> 00:10:57.429 we drop the word dollar entirely? it stays just 00:10:57.429 --> 00:11:00.289 as relevant. Right. Looking at the source, the 00:11:00.289 --> 00:11:03.629 number five remains an unshakable anchor, regardless 00:11:03.629 --> 00:11:06.330 of the noun that follows it. The concept of the 00:11:06.330 --> 00:11:08.809 five is highly adaptable. It doesn't need the 00:11:08.809 --> 00:11:11.269 franchise label of the dollar to function perfectly. 00:11:11.429 --> 00:11:13.830 We dive into the non -dollar currencies from 00:11:13.830 --> 00:11:16.850 the source, and there is this incredibly heavy 00:11:16.850 --> 00:11:19.000 presence in Latin America. We are looking at 00:11:19.000 --> 00:11:21.940 the Argentine peso, the Chilean peso, the Colombian 00:11:21.940 --> 00:11:24.259 peso, the Cuban peso. Dominican peso, Mexican 00:11:24.259 --> 00:11:27.220 peso, Uruguayan peso. Yes, and right alongside 00:11:27.220 --> 00:11:29.600 them, the Brazilian real. And the list immediately 00:11:29.600 --> 00:11:31.539 spans the globe again, jumping continents. We 00:11:31.539 --> 00:11:33.620 have the Samoan tala, the Nicaraguan cordoba, 00:11:33.779 --> 00:11:36.059 the Cape Verdean escudo. And the Tongan paonga. 00:11:36.179 --> 00:11:40.210 The Tongan paonga. The five. completely transcends 00:11:40.210 --> 00:11:44.009 linguistic and historical origins. It is as if 00:11:44.009 --> 00:11:47.610 every single culture on earth independently invented 00:11:47.610 --> 00:11:50.610 the exact same recipe for a sandwich without 00:11:50.610 --> 00:11:52.950 ever speaking to each other. That's a great analogy. 00:11:53.009 --> 00:11:55.590 Like, one culture uses a peso, one uses a reel, 00:11:55.669 --> 00:11:58.029 one uses a talla. The bread and the meat are 00:11:58.029 --> 00:12:01.330 totally different. But the foundational architecture, 00:12:01.490 --> 00:12:04.389 the five, is exactly the same everywhere you 00:12:04.389 --> 00:12:08.379 go. This raises an important question. Why? Why 00:12:08.379 --> 00:12:11.200 do human beings across the Cape Verdean Islands, 00:12:11.340 --> 00:12:14.179 off the coast of Africa, and the people of Tonga 00:12:14.179 --> 00:12:16.779 in the Pacific Ocean, and the people of Mexico 00:12:16.779 --> 00:12:19.039 all structure their localized money around this 00:12:19.039 --> 00:12:21.279 specific number? Right, because these countries 00:12:21.279 --> 00:12:23.759 have vastly different histories. Completely different. 00:12:23.779 --> 00:12:26.059 Different colonization, different paths to independence, 00:12:26.259 --> 00:12:28.080 different trading partners. Right. When you look 00:12:28.080 --> 00:12:31.120 at pesos, escudos, and cortabas, you are looking 00:12:31.120 --> 00:12:33.820 at currencies born from deeply varied cultural 00:12:33.820 --> 00:12:36.779 origins. Yet, underneath all of that cultural 00:12:36.779 --> 00:12:39.320 variance, human beings process the division of 00:12:39.320 --> 00:12:41.879 value in the exact same way. It goes back to 00:12:41.879 --> 00:12:44.620 that cognitive ease we were talking about. Exactly. 00:12:44.759 --> 00:12:47.620 It goes back to cognitive ease and working memory, 00:12:48.159 --> 00:12:51.159 specifically a concept called subitizing. Subitizing, 00:12:51.259 --> 00:12:52.700 okay. I'm gonna need you to translate that one. 00:12:52.759 --> 00:12:56.139 Yeah, so subitizing, it's the psychological term 00:12:56.139 --> 00:12:59.220 for the human ability to immediately recognize 00:12:59.220 --> 00:13:01.980 the number of objects in a small group without 00:13:01.980 --> 00:13:04.120 actually having to count them. Okay, so like 00:13:04.120 --> 00:13:06.580 just glancing at something and knowing the amount. 00:13:06.830 --> 00:13:10.049 Yes. If I threw three or four coins on a table, 00:13:10.330 --> 00:13:12.450 your brain instantly knows how many there are. 00:13:12.909 --> 00:13:15.629 But once you get past four to like six or seven 00:13:15.629 --> 00:13:18.570 items, your brain actually has to stop and physically 00:13:18.570 --> 00:13:21.690 count them. Ah. So if I'm handing over six one 00:13:21.690 --> 00:13:24.669 -dollar bills, the cashier has to stop and individually 00:13:24.669 --> 00:13:26.470 count them out. One, two, three, four, five, 00:13:26.610 --> 00:13:29.190 six. All right. But if you hand over a five and 00:13:29.190 --> 00:13:31.809 a one, the transaction is instant. The brain 00:13:31.809 --> 00:13:33.750 registers it immediately. Because it's just two 00:13:33.750 --> 00:13:36.210 objects. Exactly. Whether you are dealing in 00:13:36.210 --> 00:13:39.110 Brazilian Riales or Capri and Escudos, human 00:13:39.110 --> 00:13:42.320 working memory dictates how we trade. We fundamentally 00:13:42.320 --> 00:13:44.600 want to carry the least amount of physical objects 00:13:44.600 --> 00:13:46.840 to represent the most varied amount of value 00:13:46.840 --> 00:13:49.299 while keeping the math as simple as possible. 00:13:49.600 --> 00:13:52.159 It's all about efficiency. The five is the ultimate 00:13:52.159 --> 00:13:55.759 tool of human efficiency. It proves that despite 00:13:55.759 --> 00:13:58.399 our massive, beautiful cultural differences, 00:13:59.000 --> 00:14:01.279 when it comes to the daily reality of trading 00:14:01.279 --> 00:14:04.080 value with one another to survive, our brains 00:14:04.080 --> 00:14:07.100 all work exactly the same way. The five is the 00:14:07.100 --> 00:14:09.419 great psychological unifier. It really is. So 00:14:09.419 --> 00:14:11.659 we've established that the five is mathematically 00:14:11.659 --> 00:14:14.659 and cognitively universal. But when something 00:14:14.659 --> 00:14:17.580 becomes that physically embedded in our daily 00:14:17.580 --> 00:14:20.320 survival, it stops being just about economics. 00:14:20.620 --> 00:14:22.440 Right. It bleeds into other areas. It bleeds 00:14:22.440 --> 00:14:24.259 into our culture, which actually brings us to 00:14:24.259 --> 00:14:26.840 the final piece of this Wikipedia disambiguation 00:14:26.840 --> 00:14:31.000 page. The $5 isn't just a literal physical object 00:14:31.000 --> 00:14:32.879 used for trade anymore. No, it's bigger than 00:14:32.879 --> 00:14:35.679 that. It is such a ubiquitous, ingrained concept 00:14:35.679 --> 00:14:38.120 in our shared human experience that is actually 00:14:38.120 --> 00:14:40.600 crossed over into art. It transcends utility 00:14:40.600 --> 00:14:44.059 and becomes emotional symbolism. Yes. Down at 00:14:44.059 --> 00:14:46.120 the very bottom of the source, in the See Also 00:14:46.120 --> 00:14:48.679 section, there's an entry for a piece of music. 00:14:49.120 --> 00:14:52.279 It lists Five Dolls, which is a 2018 song by 00:14:52.279 --> 00:14:54.480 the artist Christine and the Queens. And what 00:14:54.480 --> 00:14:56.879 is so striking about that entry is that the source 00:14:56.879 --> 00:14:59.779 specifically notes it was simultaneously released 00:14:59.779 --> 00:15:03.659 in English under the title $5. A dual language 00:15:03.659 --> 00:15:06.679 release for a pop song centered entirely around 00:15:06.679 --> 00:15:09.740 a specific denomination of money. Yeah, it's 00:15:09.740 --> 00:15:12.379 fascinating. So what does this all mean? Why 00:15:12.379 --> 00:15:15.399 would a critically acclaimed artist write and 00:15:15.399 --> 00:15:20.139 name a song after such a mundane, highly specific 00:15:20.139 --> 00:15:22.860 amount of money? I mean, we write songs about 00:15:22.860 --> 00:15:24.700 being millionaires. millionaires are having no 00:15:24.700 --> 00:15:29.899 money at all. But $5, it's practically pocketlent 00:15:29.899 --> 00:15:32.000 in the grand scheme of wealth. Well, let's think 00:15:32.000 --> 00:15:34.059 about what that pocketlent actually buys you. 00:15:34.299 --> 00:15:36.279 What does a five represent to you on a Tuesday 00:15:36.279 --> 00:15:38.460 morning? I think that's exactly it. It is the 00:15:38.460 --> 00:15:41.480 ultimate everyday relatable amount. A million 00:15:41.480 --> 00:15:44.379 dollars feels abstract. It's lottery money. It's 00:15:44.379 --> 00:15:46.759 unattainable for most people. Right. And a single 00:15:46.759 --> 00:15:50.269 penny is practically worthless. But $5, that 00:15:50.269 --> 00:15:52.889 is the price of a coffee. It's the crumpled bill 00:15:52.889 --> 00:15:54.669 you find in the pocket of your winter coat when 00:15:54.669 --> 00:15:56.210 you pull it out of the closet and it makes you 00:15:56.210 --> 00:15:59.639 smile. It represents everyday human stakes. It 00:15:59.639 --> 00:16:02.840 is intimately tied to our daily survival, our 00:16:02.840 --> 00:16:05.379 small joys, our regular routines. It carries 00:16:05.379 --> 00:16:07.799 an emotional weight of accessibility. Exactly. 00:16:08.059 --> 00:16:10.220 Everyone, regardless of their background, understands 00:16:10.220 --> 00:16:13.740 the stakes of $5. And if we connect that accessibility 00:16:13.740 --> 00:16:16.379 to the dual language release of the song, $5 00:16:16.379 --> 00:16:20.259 in French and $5 in English, it perfectly mirrors 00:16:20.259 --> 00:16:22.879 the multinational nature of the currencies we 00:16:22.879 --> 00:16:24.779 just spent this whole deep dive discussing. That 00:16:24.779 --> 00:16:28.019 is brilliant. That same core concept just packaged 00:16:28.019 --> 00:16:29.779 for different audiences. Just like the money. 00:16:29.879 --> 00:16:32.700 Just like the money. The song itself acts as 00:16:32.700 --> 00:16:35.600 a metaphor for this entire conversation. It is 00:16:35.600 --> 00:16:39.200 a universal cross -cultural concept, the idea 00:16:39.200 --> 00:16:42.080 of $5 and all the everyday grit and relatability 00:16:42.080 --> 00:16:44.399 that comes with it expressed in localized ways. 00:16:44.600 --> 00:16:46.799 Wow. The artist understood that the emotional 00:16:46.799 --> 00:16:49.679 resonance of $5 translates across linguistic 00:16:49.679 --> 00:16:52.480 borders in the exact same way that the mathematical 00:16:52.480 --> 00:16:55.340 utility of the $5 note translates from the Canadian 00:16:55.340 --> 00:16:58.879 polymer bill to the Tungan palanga. A disambiguation 00:16:58.879 --> 00:17:01.399 page that starts with a simple search for a dollar 00:17:01.399 --> 00:17:04.960 amount. ends up revealing this massive map of 00:17:04.960 --> 00:17:07.599 global connection. It reminds us that money is 00:17:07.599 --> 00:17:10.099 far more than just central bank policy. It is 00:17:10.099 --> 00:17:12.420 a shared cultural language that we all speak 00:17:12.420 --> 00:17:14.500 every single day. And that brings us to the end 00:17:14.500 --> 00:17:17.259 of our journey today. We started by looking at 00:17:17.259 --> 00:17:20.460 a remarkably simple term, five dollars, and it 00:17:20.460 --> 00:17:23.400 unlocked a vast map of global trade and human 00:17:23.400 --> 00:17:25.960 behavior. We covered a lot of ground. We did. 00:17:26.680 --> 00:17:28.200 We traveled from the major English -speaking 00:17:28.200 --> 00:17:31.000 notes of the US, Australia, Canada, and New Zealand, 00:17:31.519 --> 00:17:33.519 all the way to the fascinating transitional tug 00:17:33.519 --> 00:17:36.359 of war between the coins and bills of Hong Kong. 00:17:36.480 --> 00:17:39.440 We saw the massive diaspora of the dollar stretching 00:17:39.440 --> 00:17:41.500 from the offshore wealth of the Cayman Islands 00:17:41.500 --> 00:17:43.900 to the agricultural markets of the Solomon Islands, 00:17:44.240 --> 00:17:46.839 proving that the five is a cognitive and economic 00:17:46.839 --> 00:17:49.900 inevitability. We witnessed the independent linguistic 00:17:49.900 --> 00:17:53.480 evolution of pesos, reels, talas, and escudos, 00:17:53.740 --> 00:17:55.980 showing that human logic and working memory and 00:17:55.980 --> 00:17:58.359 trade are completely universal. And finally, 00:17:58.519 --> 00:18:01.200 we saw it all reflected in a bilingual pop song 00:18:01.200 --> 00:18:03.640 that captures the everyday relatable essence 00:18:03.640 --> 00:18:06.880 of the five. It is a profound amount of hidden 00:18:06.880 --> 00:18:10.259 depth for a single digit and a dollar sign. It 00:18:10.259 --> 00:18:12.779 really is. So to you listening right now, the 00:18:12.779 --> 00:18:15.359 next time you hand over a $5 bill to a cashier 00:18:15.359 --> 00:18:18.059 or you fish a $5 coin out of your pocket for 00:18:18.059 --> 00:18:21.160 a transit ticket, I want you to picture the dozens 00:18:21.160 --> 00:18:23.960 of other iterations of that exact same concept 00:18:23.960 --> 00:18:26.940 changing hands simultaneously all over the planet. 00:18:27.000 --> 00:18:29.140 It's a powerful image. You aren't just making 00:18:29.140 --> 00:18:32.920 a small isolated purchase. You are participating 00:18:32.920 --> 00:18:36.640 in a universally shared mathematical and cultural 00:18:36.640 --> 00:18:39.500 framework. You are acting out a piece of shared 00:18:39.309 --> 00:18:41.450 human logic. But you know I want to leave you 00:18:41.450 --> 00:18:43.470 with one final thought to mull over something 00:18:43.470 --> 00:18:45.150 we haven't even touched on yet. What's that? 00:18:45.569 --> 00:18:48.230 Economies are not static they constantly shift 00:18:48.230 --> 00:18:51.009 and inflation inevitably eats away at the buying 00:18:51.009 --> 00:18:54.230 power of money over time. A century ago a five 00:18:54.230 --> 00:18:56.210 dollar bill bought a whole lot more than a quick 00:18:56.210 --> 00:18:58.430 cup of coffee. Oh absolutely. So what is the 00:18:58.430 --> 00:19:01.230 ultimate fate of the global five dollar denomination? 00:19:01.430 --> 00:19:04.809 Oh wow. That is a heavy question. As the price 00:19:04.809 --> 00:19:07.029 of that everyday coffee inevitably creeps up 00:19:07.029 --> 00:19:09.390 to six, seven, or ten dollars, what happens to 00:19:09.390 --> 00:19:11.240 the five? Right, because the math gets harder. 00:19:11.819 --> 00:19:14.359 Exactly. Will the sheer psychological weight 00:19:14.359 --> 00:19:16.759 and everyday cognitive convenience of the number 00:19:16.759 --> 00:19:19.880 five force countries to constantly revalue their 00:19:19.880 --> 00:19:22.759 entire currencies just so we can keep a useful 00:19:22.759 --> 00:19:25.839 working five in our pockets to anchor our math? 00:19:26.079 --> 00:19:29.599 Or will this ubiquitous global denomination, 00:19:29.980 --> 00:19:33.039 this universal blood type of currency eventually 00:19:33.039 --> 00:19:36.039 be rendered useless by inflation, becoming nothing 00:19:36.039 --> 00:19:38.839 more than a historical artifact? Just a memory 00:19:38.839 --> 00:19:41.900 of a time when five units of value actually meant 00:19:41.900 --> 00:19:44.420 something to our daily survival. It makes you 00:19:44.420 --> 00:19:46.279 look at that crumpled bill in your hand a whole 00:19:46.279 --> 00:19:47.779 lot differently, doesn't it? It really does. 00:19:47.900 --> 00:19:50.039 It's not just a static constant. It is an evolving 00:19:50.039 --> 00:19:52.680 piece of human history, taking the shape of whatever 00:19:52.680 --> 00:19:54.980 economic glass it's poured into, just waiting 00:19:54.980 --> 00:19:56.000 to see what the future holds.
