Dwarkesh Patel: prediction

Transcript context

…I want to give you an example. The internet has made it possible for me to do something like write a Twitter thread, get millions of people to read it, and have a discussion that's really amazing at the same time. Yet today, The Washington Post has an article about how every book in Texas (it’s one of the states) a child checks out of the school library goes into a central state databank. They can see and look for patterns of people taking out “bad books” and this sort of stuff. And I think “whoa, that's really bad! That's not so good.” It's really the same technology that brings this dissemination and collection of vast amounts of information with relative ease. So with all these things, you take the bitter with the sweet. I want to ask you again about contingency because there are so many other examples where things you thought would be universal actually don't turn out to be. I think you talked about how the natives had different forms of metallurgy, with gold and copper, but then they didn't do iron or steel. You would think that given their “warring nature”, iron would be such a huge help. There's a clear incentive to build it. Millions of people living there could have built or developed this technology. Same with the steel, same with the wheel. What’s the explanation for why these things you think anybody would have come up with didn't happen? I know. It's just amazing to me! I don't know. This is one of those things I think about all the time. A few weeks ago, it rained, and I went out to walk the dog. I'm always amazed that there are literal glistening drops of water on the crabgrass and when you pick it up, sometimes there are little holes eaten by insects in the crabgrass. Every now and then, if you look carefully, you'll see a drop of water in one of those holes and it forms a lens. And you can look through it! You can see that it's not a very powerful lens by any means, but you can see that things are magnified. So you think “How long has there been crabgrass? Or leaves? And water?” Just forever! We've had glass forever! So how is it that we had to wait for whoever it was to create lenses? I just don't get it. In book 1491, I mentioned the moldboard plow, which is the one with a curving blade that allows you to go through the soil much more easily. It was invented in China thousands of years ago, but not around in Europe until the 1400s. Like, come on, guys! What was it? And so, you know, there's this mysterious sort of mass stupidity. One of the wonderful things about globalization and trade and contact is that maybe not everybody is as blind as you and you can learn from them. I mean, that's the most wonderful thing about trade. So in the case of the wheel, the more amazing thing is that in Mesoamerica, they had the wheel on child's toys. Why didn’t they develop it? The best explanation I can get is they didn't have domestic animals. A cart then would have to be pulled by people. That would imply that to make the cart work, you'd have to cut a really good road. Whereas they had these travois, which are these things that you hold and they have these skids that are shaped kind of like an upside-down V. You can drag them across rough ground, you don't need a road for them. That's what people used in the Great Plains and so forth. So you look at this, and you think “maybe this was the ultimate way to save labor. I mean, this was good enough. And you didn't have to build and maintain these roads to make this work” so maybe it was rational or just maybe they're just blinkered. I don’t know. As for assembly with steel, I think there's some values involved in that. I don't know if you've ever seen one of those things they had in Mesoamerica called Macuahuitl. They’re wooden clubs with obsidian blades on them and they are sharp as hell. You don't run your finger along the edge because they just slice it open. An obsidian blade is pretty much sharper than any iron or steel blade and it doesn't rust. Nice. But it's much more brittle. So okay, they're there, and the Spaniards were really afraid of them. Because a single blow from these heavy sharp blades could kill a horse. They saw people whack off the head of a horse carrying a big strong guy with a single blow! So they're really dangerous, but they're not long-lasting.…
