I think the billionaire folks are pathological or opportunists, nothing really more.
As for your landlord, I doubt that will be a problem either.
You cannot make 40% - 80% of the country structurally unemployable with AI and eventually robots and keep this same economic system.
It will be weird, it’s not going to be hugely fun, but I’m betting that we either get massive deflation, huge changes in land use policy, revolution, or a combination of them all.
Personally I’m building a shack in the woods and building my own business. We will see how it turns out, but I doubt money as we know it survives this.
Edit to be clear:
I think it’s going to work out and probably be pretty cool after we deal with obvious problems that are coming up.
Things get sticky fast the longer you think on this problem and the fact leadership has always held little interest in equal distribution of the planet's spare resources vs crony corruption and nepotism. Hard to imagine a future that doesn't look like mad max outside the billionaire compounds protected by loitering robots and drones along with space based technology immune to any rebellion.
