My only concern with this, is he assumes that all that work is going to take an extremely long time and doesn't even consider the fact that it might take significantly less time than he proposes. He acknowledges this but doesn't actually go down the rabbit hole. > Remediating climate change will involve unimaginably labor-intensive tasks, like relocating every coastal city in the world kilometers inland, building high-speed rail links to replace aviation links, caring for hundreds of millions of traumatized, displaced people, and treating runaway zoontoic and insectborne pandemics. This does sound like a lot of work, but realistically it's like, what... maybe 10-20 years worth of actual human labor at current levels? Our capacity is so enormous that probably 90% of the things you'll interact with today were created in the past 10 years. If machines are slated to replace that amount of manufacturing, imagine the labor that would be displaced! If we could hypothetically throw double the labor into these projects than before these cities would go up instantly. Like Chinese Ghost cities. Our civilization is already built. Most of the work went into building the required tools and technology which enable us to do more with less. Building skyscrapers is just large scale Legos when you have the right tools. What took Egyptians thousands of people now takes about 12 equipment operators. Now that we have those tools, now that we've commoditized them all this isn't really a "daunting" task for us as a species. Societally it presents new challenges, but humans are nothing if not resilient.
