WEBVTT 00:00:00.000 --> 00:00:02.779 Welcome back to the deep dive. You know, we love 00:00:02.779 --> 00:00:06.540 finding a really simple way to frame an overwhelmingly 00:00:06.540 --> 00:00:10.720 complex system. And today we are appearing deep 00:00:10.720 --> 00:00:12.800 into the architecture of modern communication, 00:00:12.800 --> 00:00:16.399 but we're using a lens that's entirely human. 00:00:16.589 --> 00:00:18.510 We're talking about computers that listen and 00:00:18.510 --> 00:00:21.089 computers that shout. Our mission today is really 00:00:21.089 --> 00:00:23.910 to synthesize that massive evolutionary jump 00:00:23.910 --> 00:00:28.149 in communication. I mean, from simple ephemeral 00:00:28.149 --> 00:00:31.629 sound waves to the instant global electronic 00:00:31.629 --> 00:00:34.009 signals that define our lives in the 21st century. 00:00:34.369 --> 00:00:36.429 When you look at all the complex systems connecting 00:00:36.429 --> 00:00:39.109 us, the networks, the servers, that tiny device 00:00:39.109 --> 00:00:41.560 in your pocket, it... it actually helps to think 00:00:41.560 --> 00:00:44.579 about them in these very human terms. We're contrasting 00:00:44.579 --> 00:00:47.619 the finite limits of our own biology with the 00:00:47.619 --> 00:00:49.939 boundless reach of technology. And to really 00:00:49.939 --> 00:00:52.259 understand the magnitude of that shift, I think 00:00:52.259 --> 00:00:53.880 we have to start with the human baseline. Where 00:00:53.880 --> 00:00:56.039 we came from. Exactly. When you strip away all 00:00:56.039 --> 00:00:58.140 the innovations, all the tech, human communication 00:00:58.140 --> 00:01:00.079 basically rests on two systems. The first one 00:01:00.079 --> 00:01:03.070 is the most basic. speech and hearing. That's 00:01:03.070 --> 00:01:04.950 the default human setting, right? Absolutely. 00:01:05.609 --> 00:01:09.090 Speech is, by its very nature, ephemeral. If 00:01:09.090 --> 00:01:10.629 I say something right now and you don't hear 00:01:10.629 --> 00:01:12.870 it, well, it's just gone forever. It's local. 00:01:13.090 --> 00:01:15.370 It only works over pretty short distances, you 00:01:15.370 --> 00:01:17.590 know, limited by my voice and the room we're 00:01:17.590 --> 00:01:21.030 in. The upside, though, it requires only our 00:01:21.030 --> 00:01:23.969 basic anatomy. It develops with basically no 00:01:23.969 --> 00:01:26.590 special training. It's just foundational. So 00:01:26.590 --> 00:01:29.829 quick, local, and temporary. We needed something 00:01:29.829 --> 00:01:31.430 more permanent, something that could go further, 00:01:31.469 --> 00:01:33.450 and that, I assume, brings us to the second system, 00:01:34.090 --> 00:01:36.750 writing. Writing and reading fundamentally changed 00:01:36.750 --> 00:01:39.329 the game. I mean, this system extended communication 00:01:39.329 --> 00:01:41.930 over distance, and maybe even more crucially, 00:01:42.230 --> 00:01:45.670 over time. Time. Right, messages became permanent, 00:01:45.969 --> 00:01:48.510 repeatable, transportable. One of the most fascinating 00:01:48.510 --> 00:01:51.430 ideas we pulled from the material is this concept 00:01:51.430 --> 00:01:54.209 that writers are, in essence, communicating with 00:01:54.209 --> 00:01:56.930 readers who are situated in the future. Communication 00:01:56.930 --> 00:01:59.200 through time. It's wild to think about that. 00:01:59.280 --> 00:02:02.099 You write down a law, a story, a philosophical 00:02:02.099 --> 00:02:04.379 text. You're basically projecting your voice 00:02:04.379 --> 00:02:06.640 hundreds, maybe thousands of years forward. It's 00:02:06.640 --> 00:02:09.860 the ultimate legacy system. It is. It's how civilizations 00:02:09.860 --> 00:02:14.120 persist. But, and here's the rub, even with writing... 00:02:13.900 --> 00:02:16.580 And later, you know, print, which let us make 00:02:16.580 --> 00:02:19.639 countless identical copies, the speed was still 00:02:19.639 --> 00:02:23.000 fundamentally limited. How so? It was bound by 00:02:23.000 --> 00:02:25.300 the speed at which that physical object, the 00:02:25.300 --> 00:02:28.000 paper or the tablet, could be physically transported. 00:02:28.539 --> 00:02:30.699 Think about that for a moment. For millennia, 00:02:31.139 --> 00:02:33.379 the speed of information was literally the speed 00:02:33.379 --> 00:02:37.319 of a horse or the fastest ship or a runner communicating 00:02:37.319 --> 00:02:39.379 from Rome to London. You're measuring that in 00:02:39.379 --> 00:02:41.780 weeks, maybe months. That governed everything. 00:02:41.979 --> 00:02:45.099 Commerce, politics, war. And this is where that 00:02:45.099 --> 00:02:47.240 speed limit, the speed of transport, imposed 00:02:47.240 --> 00:02:49.979 this profound constraint, both logistically and 00:02:49.979 --> 00:02:52.379 I think psychologically. You had to really commit 00:02:52.379 --> 00:02:55.060 to a message knowing the reply might take an 00:02:55.060 --> 00:02:57.840 eternity. Information traveled at the speed of 00:02:57.840 --> 00:03:00.599 matter. OK, so let's unpack this. If transportation 00:03:00.599 --> 00:03:02.919 was the ultimate speed limit for almost all of 00:03:02.919 --> 00:03:05.400 human history, what happens when time and distance 00:03:05.400 --> 00:03:08.360 aren't just shortened, but effectively annihilated? 00:03:08.639 --> 00:03:10.520 That's the moment the electrons enter the conversation. 00:03:10.719 --> 00:03:13.039 And what's so fascinating here is just how quickly 00:03:13.039 --> 00:03:15.439 the world shrank once we harnessed electrical 00:03:15.439 --> 00:03:18.479 signals. The source material points specifically 00:03:18.479 --> 00:03:21.379 to the telegraph. This machine carried messages 00:03:21.379 --> 00:03:23.800 across continents and eventually under oceans 00:03:23.800 --> 00:03:26.340 with what people at the time called unimaginable 00:03:26.340 --> 00:03:29.460 speed. We have to pause on that word. Unimaginable. 00:03:29.740 --> 00:03:33.400 For someone in, say, 1840, the idea you could 00:03:33.400 --> 00:03:35.900 communicate across 3 ,000 miles in a few seconds 00:03:35.900 --> 00:03:37.930 would have sounded like magic. or maybe something 00:03:37.930 --> 00:03:40.849 demonic. Suddenly, the only delay wasn't the 00:03:40.849 --> 00:03:43.689 journey. It was just a brief moment for a human 00:03:43.689 --> 00:03:46.669 to encode and decode the message. Tap, tap, tap. 00:03:46.969 --> 00:03:49.710 The physical barrier of space was just gone. 00:03:50.189 --> 00:03:52.539 Precisely. And that revolutionary shift, it leads 00:03:52.539 --> 00:03:54.860 directly to this concept of the global village. 00:03:55.020 --> 00:03:57.819 The term really captures this new reality that 00:03:57.819 --> 00:04:00.020 with electronic communication, everyone on the 00:04:00.020 --> 00:04:03.259 planet can effectively be within earshot of everyone 00:04:03.259 --> 00:04:05.300 else. That's a powerful metaphor, within earshot. 00:04:05.560 --> 00:04:07.860 It really is, because it connects that local, 00:04:08.080 --> 00:04:10.780 instinctual feeling of human speech. Being able 00:04:10.780 --> 00:04:14.479 to call out and be heard to a global infrastructure. 00:04:14.909 --> 00:04:17.589 And this applies from the very first telegraphs 00:04:17.589 --> 00:04:20.050 all the way up to our 21st century satellite 00:04:20.050 --> 00:04:23.550 -mediated world. That instant collapse of distance, 00:04:23.930 --> 00:04:26.250 it's foundational to understanding modern life. 00:04:26.389 --> 00:04:29.410 It forces us to deal with events instantly, no 00:04:29.410 --> 00:04:31.850 matter where they happen. So if the telegraph 00:04:31.850 --> 00:04:33.930 was the first electronic whisper across the ocean, 00:04:34.529 --> 00:04:38.189 today, the global shouting, this instantaneous 00:04:38.189 --> 00:04:40.410 capacity, it's become completely commonplace. 00:04:40.649 --> 00:04:42.470 Let's focus on the main instrument for this in 00:04:42.470 --> 00:04:45.529 the 21st century, the smartphone. The data suggests 00:04:45.529 --> 00:04:47.329 there are something like two billion of these 00:04:47.329 --> 00:04:49.110 devices out there. These are our personal tools 00:04:49.110 --> 00:04:51.769 for shouting. The scale is just astronomical. 00:04:52.069 --> 00:04:54.029 And it's a complex shout, too. It's not just 00:04:54.029 --> 00:04:56.829 a single acoustic sound. With these devices, 00:04:56.829 --> 00:04:59.290 you can compose a message in so many formats, 00:04:59.490 --> 00:05:02.449 text, an image, audio, a video, and send it instantly. 00:05:02.829 --> 00:05:05.569 The power isn't just in the speed. It's the reach 00:05:05.569 --> 00:05:08.220 and the modality, like you said. You can send 00:05:08.220 --> 00:05:10.439 that rich message to a few people, or you can 00:05:10.439 --> 00:05:12.459 blast it out to servers on the World Wide Web. 00:05:12.899 --> 00:05:14.699 Share it with anyone in the world who can find 00:05:14.699 --> 00:05:17.800 it. That's why we call it Shouting. It's designed 00:05:17.800 --> 00:05:21.029 for maximum reach with minimal effort. And we 00:05:21.029 --> 00:05:23.250 experience this every day, right? Often, without 00:05:23.250 --> 00:05:25.649 even realizing how truly phenomenal it is when 00:05:25.649 --> 00:05:27.509 you look at it against the backdrop of human 00:05:27.509 --> 00:05:30.709 history. Our sources give some great, really 00:05:30.709 --> 00:05:33.829 specific examples that show just how routine 00:05:33.829 --> 00:05:36.410 this global shouting has become. Okay, think 00:05:36.410 --> 00:05:39.149 about watching a big, broadcasted sporting event. 00:05:39.370 --> 00:05:41.689 You're on the West Coast, your friend is on the 00:05:41.689 --> 00:05:44.370 East Coast, and you're sending real -time texts, 00:05:44.629 --> 00:05:47.649 videos, jokes back and forth as the game unfolds. 00:05:47.709 --> 00:05:49.769 That's shouting across a continent in perfect 00:05:49.769 --> 00:05:52.740 sync. Or, what about the professional absurdities 00:05:52.740 --> 00:05:55.860 we all accept now? A huge team project, and one 00:05:55.860 --> 00:05:57.980 person needs to update the boss on some system 00:05:57.980 --> 00:06:00.000 upgrades. They're in an office in New England 00:06:00.000 --> 00:06:02.500 and the boss is in a hotel room in, I don't know, 00:06:02.660 --> 00:06:05.079 Helsinki, Finland, and they just slumped video 00:06:05.079 --> 00:06:07.779 chat. The physical locations are totally irrelevant. 00:06:08.339 --> 00:06:11.019 The message is instant and rich with detail. 00:06:11.620 --> 00:06:13.860 Or in a meeting, you could be in a conference 00:06:13.860 --> 00:06:16.620 room in Texas talking with people who are simultaneously 00:06:16.620 --> 00:06:19.240 in New York and California and maybe even Sydney. 00:06:19.389 --> 00:06:22.170 Wow. The time zones are the only real friction 00:06:22.170 --> 00:06:24.509 left. And this is where it gets really interesting 00:06:24.509 --> 00:06:27.990 for me. These mundane everyday interactions show 00:06:27.990 --> 00:06:30.949 that our shouting is no longer bound by local 00:06:30.949 --> 00:06:34.730 acoustics or a printed page or even oceans. We 00:06:34.730 --> 00:06:38.009 are constantly tirelessly and instantly shouting 00:06:38.009 --> 00:06:41.069 across the entire planet. The world genuinely 00:06:41.069 --> 00:06:44.069 has become within earshot of every citizen. And 00:06:44.069 --> 00:06:45.709 for every shout, there has to be a listener. 00:06:46.189 --> 00:06:48.910 Which brings us to the second, and I think maybe 00:06:48.910 --> 00:06:51.350 the more profound, half of this whole analogy. 00:06:51.709 --> 00:06:53.709 Exactly. It's easy to focus on the sending, on 00:06:53.709 --> 00:06:55.829 the shouting, but the listening capacity of these 00:06:55.829 --> 00:06:58.350 devices is the real game changer. Just think 00:06:58.350 --> 00:07:01.350 about the sheer volume. Uncountable emails, texts, 00:07:01.769 --> 00:07:03.910 social media posts, all flying across the internet 00:07:03.910 --> 00:07:06.589 at any given moment. The typical user might have 00:07:06.589 --> 00:07:08.790 hundreds of messages meant just for them every 00:07:08.790 --> 00:07:11.550 single day. If we had to rely on human listening... 00:07:11.600 --> 00:07:13.680 I mean, a person sitting there actually monitoring 00:07:13.680 --> 00:07:16.120 all those channels, they would collapse from 00:07:16.120 --> 00:07:18.759 exhaustion in a few hours. This is where the 00:07:18.759 --> 00:07:21.199 device's ability just dramatically surpasses 00:07:21.199 --> 00:07:24.100 our own limitations. Electronic devices listen 00:07:24.100 --> 00:07:27.339 with much more precision and with far, far greater 00:07:27.339 --> 00:07:30.040 patience and energy than any human possibly could. 00:07:30.699 --> 00:07:33.199 Precision is a huge point. If I'm in a loud room 00:07:33.199 --> 00:07:34.959 trying to listen to three different conversations, 00:07:35.300 --> 00:07:37.180 I'm going to miss details, I'll get distracted, 00:07:37.360 --> 00:07:40.040 I'll prioritize poorly. A phone doesn't have 00:07:40.040 --> 00:07:41.819 those problems. It doesn't. And the mechanics 00:07:41.819 --> 00:07:44.459 are really sophisticated. Your phone is configured 00:07:44.459 --> 00:07:47.899 not just to passively receive. It actively listens 00:07:47.899 --> 00:07:50.379 for specific messages meant for you, and then 00:07:50.379 --> 00:07:53.399 it notifies you. And crucially, it's contextual. 00:07:53.839 --> 00:07:56.199 It pays attention to who the sender is, the channel 00:07:56.199 --> 00:07:59.399 email, text, and app, and the nature of the message 00:07:59.399 --> 00:08:02.279 itself. And it varies the notification. A call 00:08:02.279 --> 00:08:04.360 from your kid might get a loud ring overriding 00:08:04.360 --> 00:08:07.300 a simple text from a mailing list. That detail, 00:08:07.660 --> 00:08:10.209 varying the notification. based on context. That's 00:08:10.209 --> 00:08:13.209 key. It's not just a dumb receiver. It's an active 00:08:13.209 --> 00:08:15.629 sorter. It's a prioritizer. We're outsourcing 00:08:15.629 --> 00:08:18.050 our attention filtering to the machine. But the 00:08:18.050 --> 00:08:20.850 real game changer, the profound difference, is 00:08:20.850 --> 00:08:23.509 just the tireless nature of the listening. Absolutely. 00:08:23.870 --> 00:08:26.050 The device listens for messages when the human 00:08:26.050 --> 00:08:28.769 is sound asleep, or busy, or just completely 00:08:28.769 --> 00:08:31.069 disconnected from a conversation. The phone never 00:08:31.069 --> 00:08:33.009 says, you know what, I'm tired. I'll check those 00:08:33.009 --> 00:08:35.250 tomorrow. And it listens to many channels at 00:08:35.250 --> 00:08:37.639 once. When you're asleep, your conscious brain 00:08:37.639 --> 00:08:40.500 is tuned out, but your phone is wide awake. It's 00:08:40.500 --> 00:08:43.519 simultaneously monitoring email, text, five social 00:08:43.519 --> 00:08:46.480 media feeds, app notifications. We've achieved 00:08:46.480 --> 00:08:49.600 simultaneous multi -channel tireless listening. 00:08:49.960 --> 00:08:51.679 And if you connect this to the bigger picture, 00:08:52.000 --> 00:08:54.409 this ability to listen without exhaustion. It 00:08:54.409 --> 00:08:56.309 profoundly changes our relationship with the 00:08:56.309 --> 00:08:59.629 flow of information. A human listener is finite. 00:09:00.230 --> 00:09:02.629 An electronic listener is effectively infinite 00:09:02.629 --> 00:09:04.950 in its capacity for precision and endurance. 00:09:05.450 --> 00:09:07.990 It guarantees our presence, even in our physical 00:09:07.990 --> 00:09:10.889 absence. So we've established the shout instant, 00:09:11.269 --> 00:09:13.929 global, multimodal, and the listen tireless, 00:09:14.269 --> 00:09:17.809 precise, and multi -channel. So what does this 00:09:17.809 --> 00:09:21.009 capacity actually mean in a real world context? 00:09:21.909 --> 00:09:24.870 The source material specifically points out how 00:09:24.870 --> 00:09:27.789 this is leveraged in education. Education is 00:09:27.789 --> 00:09:30.389 the perfect application, really, because it traditionally 00:09:30.389 --> 00:09:33.149 relied so heavily on that localized, ephemeral 00:09:33.149 --> 00:09:35.809 classroom model. The teacher speaking to the 00:09:35.809 --> 00:09:38.389 student face -to -face within a set hour. The 00:09:38.389 --> 00:09:40.669 listening and shouting capabilities just completely 00:09:40.669 --> 00:09:43.009 transcend that. So how does it extend the reach 00:09:43.009 --> 00:09:45.570 of the school? Well, you see immediate value 00:09:45.570 --> 00:09:48.230 in collapsing distance and time. First, educators 00:09:48.230 --> 00:09:50.389 and students can share details of classroom events 00:09:50.389 --> 00:09:52.370 instantly with the whole school community or 00:09:52.370 --> 00:09:54.710 with parents. More fundamentally, they can learn 00:09:54.710 --> 00:09:56.870 about world events just as they're happening, 00:09:57.070 --> 00:09:59.909 not days later. The classroom becomes globally 00:09:59.909 --> 00:10:02.809 responsive. That turns it into a real -time observation 00:10:02.809 --> 00:10:05.149 post, not just a place where history is discussed 00:10:05.149 --> 00:10:08.110 after the fact. Exactly. But maybe the most important 00:10:08.110 --> 00:10:10.309 application is extending the classroom community 00:10:10.309 --> 00:10:13.210 beyond the physical limits of the campus itself. 00:10:13.629 --> 00:10:16.789 Extending it to who? Like mentors or experts? 00:10:17.090 --> 00:10:19.519 Precisely. This technology allows the classroom 00:10:19.519 --> 00:10:22.659 to include vital resources like mentors, experts, 00:10:22.820 --> 00:10:25.279 peers, regardless of their physical location 00:10:25.279 --> 00:10:27.820 or their time zone. A student researching marine 00:10:27.820 --> 00:10:31.320 biology can communicate in real time or asynchronously 00:10:31.320 --> 00:10:34.100 with an expert who's actually studying the Great 00:10:34.100 --> 00:10:37.220 Barrier Reef. The ability to collaborate on projects 00:10:37.220 --> 00:10:39.899 across the globe becomes instantaneous. So instead 00:10:39.899 --> 00:10:42.299 of being limited to the expertise available within, 00:10:42.299 --> 00:10:44.379 you know, a five -mile radius of the school, 00:10:44.840 --> 00:10:47.080 the classroom can tap into the entire World Wide 00:10:47.080 --> 00:10:50.210 Web. Learning is no longer restricted to a building 00:10:50.210 --> 00:10:52.830 between certain hours. It transforms education 00:10:52.830 --> 00:10:55.970 from a finite event into a continuous conversation. 00:10:56.549 --> 00:10:58.990 This capacity to collapse distance and time, 00:10:59.129 --> 00:11:01.330 it completely transforms the traditional structure 00:11:01.330 --> 00:11:03.649 of learning. We're moving from the finite classroom 00:11:03.649 --> 00:11:05.710 to the infinite connected learning community. 00:11:06.039 --> 00:11:08.139 And that brings us to the end of our deep dive 00:11:08.139 --> 00:11:10.799 today. We started with the physical limits of 00:11:10.799 --> 00:11:12.600 the human body, ephemeral speech and written 00:11:12.600 --> 00:11:15.759 print, communication bound by the speed of transport. 00:11:16.059 --> 00:11:18.600 And we finished with 21st century devices that 00:11:18.600 --> 00:11:21.440 are capable of global instantaneous shouting, 00:11:21.980 --> 00:11:24.340 complimented by hyper precise multi -channel 00:11:24.340 --> 00:11:26.850 listening that quite literally never sleeps. 00:11:27.629 --> 00:11:29.730 We've gone from the human voice, which required 00:11:29.730 --> 00:11:32.269 no special training, but was purely local and 00:11:32.269 --> 00:11:34.830 temporary, to a technological extension of our 00:11:34.830 --> 00:11:37.840 senses that is global, immediate, permanent. 00:11:38.059 --> 00:11:40.220 It's a mind -bending shift and it happened in 00:11:40.220 --> 00:11:42.360 less than two centuries. And this raises the 00:11:42.360 --> 00:11:44.659 final question for you, the listener, to mull 00:11:44.659 --> 00:11:47.539 over. If human attention and physical presence 00:11:47.539 --> 00:11:49.899 are inherently finite, you know, we need sleep, 00:11:49.899 --> 00:11:51.960 we get distracted, we can only monitor so much 00:11:51.960 --> 00:11:54.580 at once, what are the true implications when 00:11:54.580 --> 00:11:56.820 technology is configured to possess infinite 00:11:56.820 --> 00:11:59.559 patience and energy for listening? What happens 00:11:59.559 --> 00:12:01.799 to our right to be absent or our expectation 00:12:01.799 --> 00:12:03.779 of silence when the machine never stops paying 00:12:03.779 --> 00:12:06.139 attention? That's the boundary we're all living 00:12:06.139 --> 00:12:06.799 on right now.
