Machines could make half of humans unemployed in 30 years
Wasn't that said 30 years ago? Are half the number of humans on the planet that are now unemployed, the same number as 30 years ago? Yeah, probably. Because at least half the world's population lives in poverty, even those who have low-wage jobs. It's tit-for-tat.
Machines will not make "half the world's population unemployed." People will.
