I honestly have no clue. Predicting the economy is impossible, especially when you can't really predict the variables. I'm looking for an answer that makes sense instead of the same ideas that don't.

It doesn't make sense to increase productivity and output in tandem with humans infinitely. Not only will AI have much higher intellect than humans, most humans won't be able to do highly intellectual jobs. So that leaves labour and skilled positions that AI haven't been able to automate and only a handful of people can do. The labour careers won't have high salaries, especially if they could be replaced with automated systems but it's just due to cost.

So we will live in a world where the majority is working low wage, unskilled jobs while companies produce an over-abundance of products that people can't afford? Who will their customers be?

You could argue automation would decrease prices, but that decreases prices of robots because they're essentially a product to be produced, and that makes low skilled labourers' cost more than automation.

I haven't heard much that's more convincing than just enjoying leisure time, even though that feels like a pipe dream.
