Not many. I think the pandemic proved that. Now shit jobs are finding it hard to fill vacancies, and I can only wonder why it took so long for everyone to realize that the game is fucking rigged.
That's why I support UBI. I don't know if it can work economically. But I think we're approaching a point where we need to acknowledge something crackpots like me have been saying for years: most jobs are pointless. Let the robots do what they can, and the rest of us can write and paint and come up with dope TikTok dances.
