> what happens when it doesn't?
It will never happen. Capitalism works when consumers can choose the best service provider. When there is only one universal service provide (AI), behind various "fronts", it would be catastrophic.
And all the consumers lose catastrophically.
So there should be at least some human component to differentiate between the various "AI" providers.
That’s a should, what makes it a will? Capitalism can just be killed by AI.
But if the AIs learn from the business (at some point they need to) then the differentiator get's absorbed back. If you figure out how to optimize your AI/humanoid robot, that benefit you have only lasts until the next AI model that incorporates your successes.
