Lot's of people wouldn't work. So we'll need robots, automation and AI to be ready to step in. Thankfully, we're getting close.Would it work for everyone? Not at all. Would it work for some? Absolutely, I personally love doing yard work and landscaping type work but it won’t pay me enough to survive. Much like I’m sure some other people enjoy the not so glamour jobs.
If I didn’t have to worry about money again, I’d take on a crappier paying job.
Hell if I didn’t have to worry about money, I’d dig through peoples trash.
Lots of people would still work. But we'd all be in the position of gentleman scientists or gentleman farmers and whatnot from yesteryear. We'd pursue hobbies and interests. And we might even produce fine art, theories, writings, discoveries, and more.
The important difference would be that we'd do that work because we want to, not because we have to.
That's a wonderful future to contemplate.
