They say in the post that exponentially declining population will eventually outweigh any linear productivity increases and then the economy will start to shrink. Is this empirically correct? How fast does productivity per person grow? Anyway, this is irrelevant in my opinion when we are <20 years away from transformative AI, which might automate many jobs and allow more leisure/​retirement (among other possibilities).
