> what sorts of new economic models will be needed to help everyone thrive in a post-scarcity world
What sort of new economic models did we come up with to help everyone thrive in a post-X world? Like, food production is really a solved technical problem. We can feed anyone on the planet if we wanted to. Another example: we could put everyone who's homeless into some sort of a house. Have we done that yet?
Post-scarcity? Sure, if you live in a first-world country and are upper middle class or higher. These tech-bro pundits have a very limited world view. The basic essentials of life are very scarce for millions and millions of people, and AI will probably make that worse, not better.
Food production is indeed a solved problem in most countries (we are almost post-scarcity when it comes to food), which is why obesity is a much bigger issue than hunger today. Hunger is present pretty much only in conflict zones. I fully expect such issues in conflict zones, even in AI post-scarcity world.
Housing is definitely not post-scarcity today, building a house is still very expensive, not to mention the limited availability of land zoned for housing.
