Yeah, from the perspective of the ultra-wealthy us humans are already pretty worthless and they'll be glad to get rid of us.
But from the perspective of a human being, an animal, and the environment that needs love, connection, mutual generosity and care, another human being who can provide those is priceless.
I propose we break away and create our own new economy and the ultra-wealthy can stay in their fully optimised machine dominated bunkers.
Sure maybe we'll need to throw a few food rations and bags of youthful blood down there for them every once in a while, but otherwise we could live in an economy that works for humanity instead.
The thing that the ultra-wealthy desire above all else is power and privilege, and they won't be getting either of that in those bunkers.
They sure as shit won't be content to leave the rest of us alone.
