“continue to be efficient and continue to increase in the future because it just makes sense and then there's a separate question of well suppose you didn't do any of that like suppose you just tried to imagine the most rudimentary the most narrowest possible kind of infrastructure build out and deployment that would be sufficient to get this pause the feedback loop that leads to like much more efficient AIs I agree that loop could in principle”

“be much smaller than the entire world.”
