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.
