Isn’t this position predicated on the assumption that individuals without substantial capital “own” an AI?
When someone uses an AI they do not own, they are (maybe) receiving a benefit in exchange for improving that AI and associated intellectual property / competitive advantage of the person or entity that owns the AI—-and subsequently improving the final position of the AI’s owner.
The better an AI becomes, the more valuable it becomes, and the more likely that the owner of the AI would want to either restrict access to the AI and extract additional value from users (e.g. via paid subscription model) or leverage the AI to develop new or improve existing revenue streams—-even if doing so is to the detriment of AI users. After all… a sufficiently-trained “AGI” AI could (in theory) be capable of outsmarting anyone that uses it, know more about its users than its users consciously know about themselves, and could act faster than any human.
While I share in your hope, I think it is unfortunately far more likely that AIs will widen the gap between the haves and the have-nots and will evolve into some of the most financially and intellectually oppressive technology ever used by humans (willingly or not).
