But that's just the thing: OpenAI isn't supposed to have a product. They're supposed to offer a benefit to humankind.
The problem is that they have a for-profit arm.
If investors didn't get any benefits ("richer" in your parlance) why should they invest?
If they didn't invest where would the money come from? tax dollar? Can you envision tax dollar be spent on AI research? or would they bring ChatGPT as quickly or as capable?
