Dwarkesh Patel: recommendation

Transcript context

Today, I have the pleasure of speaking with Brian Potter, who is an engineer and the author of the excellent Construction Physics blog, where he writes about how the construction industry works and why it has been slow to industrialize and innovate. It's one of my favorite blogs on the internet, I highly, highly recommend that people check it out. Brian, my first question is about The Line project in Saudi Arabia. What are your opinions? It's interesting how Saudi Arabia and countries in the Middle East, in general, are willing to do these big, crazy, ambitious building projects and pour huge amounts of money into constructing this infrastructure in a way that you don't see a huge amount in the modern world. China obviously does this too in huge amounts, some other minor places do as well, but in general, you don't see a whole lot of countries building these big, massive, incredibly ambitious projects. So on that level, it's interesting, and it's like, “Yes, I’m glad to see that you're doing this,” but the actual project is clearly insane and makes no sense. Look at the physical arrangement layout–– there's a reason cities grow in two dimensions. A one-dimensional city is the worst possible arrangement for transportation. It’s the maximum amount of distance between any two points. So just from that perspective, it's clearly crazy, and there's no real benefit to it other than perhaps some weird hypothetical transportation situation where you had really fast point-to-point transportation. It would probably be some weird bullet train setup; maybe that would make sense. But in general, there's no reason to build a city like that. Even if you wanted to build an entirely enclosed thing (which again doesn't make a huge amount of sense), you would save so much material and effort if you just made it a cube. I would be more interested in the cube than the line. [laughs] But yeah, those are my initial thoughts on it. I will be surprised if it ever gets built.…
