When you get more marginal product from an input, it's expected you buy more of that input.
But at some point, if the marginal product gets high enough, the world needs not as many, because money spent on other inputs/factors pays off more.
This is a classic problem with extrapolation. Making people more efficient through the use of AI will tend to increase employment... until it doesn't and employment goes off a cliff. Getting more work done per unit of GPU will increase demand for GPUs ... until it doesn't, and GPU demand goes off the cliff.
It's always hard to tell where that cliff is, though.
