OpenAI and Anthropic's valuations are based on the idea that once you get AGI, you can use the AI to maintain, improve, and upgrade itself. The capitalist-controlled AGI will build them fully autonomous dark factories and maintenance depots, so they can build and maintain a robot fleet without any humans. Who cares when a robot breaks if you can swap it out immediately with a new one and take the old one back to your robotic maintenance depot to be torn down and recycled?
I never said that this is a realistic solution, but this is absolutely the only way capitalists can solve the worker-capitalist divide forever in their favor. If they still need any workers, then we still have negotiating power, so they absolutely want to get rid of every last one of us.
