With the world’s population projected to severely contract in the coming centuries, I wonder how that will effect the possibility of exponential growth.

General artificial intelligence, once we figure it out, will cause an increase in the annual economic growth more extreme than even the industrial revolution caused. Either that or a disaster, but hopefully the former.

Anyone who thinks we will run out of things to create just lacks imagination. There's so much stuff we'd really, really like to have but haven't been able to economically create yet. Medicine, body modifications, automation of all that's boring, cheaper manufacturing of everything, entertainment, recreation, transport, space habitats and almost anything else you can imagine.

But as things get automated and cheaper that’s actually negative gdp growth. So it won’t pay your retirement

If things get cheaper, you can live off less income from your investments .

Yep, and in such a world, a reasonable level of taxation would eventually be able to pay for a modest lifestyle for everyone who wanted it.

In a world of such dramatic surplus, it's either that or violent revolution, so I'm fairly sure it would sort itself out.
