AI cannot dig ditches. AI cannot harvest crops. AI cannot frame a house, fix a car, or do anything else in the real, physical world. It will never do these things, not because of technical limitations, but because human labor is cheap and versatile.
AI can only really take the jobs of those who sit at a computer all day. Even then, I suspect that the only people who really need to worry over the long term are middle management. And good riddance to them.
But either way, there will be no UBI, so don't hold your breath. Our leadership will let us all starve in the streets the second we are no longer required.
And you better believe I will ride around on a fucking HORSE before I put up with ads on my dashboard. Screw that noise.
