Or imagine a world where we could basically cure every disease? Or a world where people could assume any form factor that they wanted? I don't know, the list goes on and on in a post-scarcity world... and we're seeing how we basically live in a sort of digital post-scarcity now and it is really cool.
If I need a software tool these days I don't buy it, I tend to see if I can make it. Now imagine that for physical things? What a time to be alive.
We also have humans who essentially live post scarcity lives on the back of a monetary windfall, yet their stories are strangely quite often depressing ones.
I think their is good reason to believe most human desires are illusions.
