>There isn’t a rule of economics that says better technology makes more, better jobs for horses. It sounds shockingly dumb to even say that out loud, but swap horses for humans and suddenly people think it sounds about right.

--CGPGrey, Humans need not apply.

You need a paradigm shift in your mind on why the modern world looks like it does. You don't need human consumers, you just need a consumer. Any system that allows you to get the hard resources you need to produce the hard/soft resources required is simply enough. Humans are fungible for anything else that can provide manual or intellectual labor.

As a thought excercize, just imagine a bunch of AIs/robots buying/selling/trading resources between each other. Where are humans required in this?
