When you think about it, we're only "useful" to billionaires because we have something that they want, and that something is not called "work". Work is just that thing that people must figure out before they can generate wealth. Money is the goal, work is just something in the way.

As most human tasks are automated away, the bargaining power of the (figurative) 99.9% of people who were actually producing wealth by doing actual work will converge towards zero.

I wish I had something positive to share, but if you don not happen to be a billionaire, then the future looks grim.
