Whoa there internet friend! I don't think I said anything about wealth concentration not being a trend. I'm just talking about AI. I'm still waiting for someone to explain coherent, undeniable watertight reasons that we're on a one-way track that goes from AI companies to infinite money glitch or robot death factories. I've already made my arguments against why I don't think it will happen before[0][1]
Maybe the argument is some already-rich fella with magic robot factories will have everything they will ever need, so they brush away all of humanity like an unsightly bit of dandruff on their shoulder with their kill bot drone army.
I guess if you squint at it long enough, that kinda sounds plausible. In the same way someone could press a giant red nuke button and have us all wiped out like a Terminator movie. But it's making a lot of fantastic assumptions without a lot of concreteness. That is, many people seem to be claiming "this is the AI endgame" rather than seeing other possibilities that aren't so ridiculously cynical or nihilistic with leaky abstractions
