Cost disease in half the economy will slow AI-driven growth

From the conversation

It's very hard to get explosive economic growth for any reason, AI or not. One problem is that some parts of your economy grow very rapidly, and then you get a cost disease in the other parts of your economy that, for instance, can't use AI very well. Look at the US economy. These numbers are guesses, but government consumption is what, 18%? Healthcare is almost 20%. I'm guessing education is 6 to 7%. The nonprofit sector, I'm not sure the number, but you add it all up, that's half of the economy right there. How well are they going to use AI? Is failure to use AI going to cause them to just immediately disappear and be replaced? No, that will take, say, 30 years. So you'll have some sectors of the economy, less regulated, where it happens very quickly. But that only gets you a modest boost in growth rates, not anything like the whole economy grows 40% a year. The mechanism behind cost disease is that there's a limited amount of laborers, and if there's one high productivity sector, then wages everywhere have to go up. So your barber also has to earn twice the wages or something. With AI, you can just have every barbershop with 1,000 times the workers, every restaurant with 1,000 times the workers, not just Google. So why would the cost disease mechanism still work here? Cost disease is more general than that.…
