I think you're missing that Sam Altman is very smart. If OpenAI really were on the verge of becoming massively profitable due to their next-gen AI, he would not want that information leaking. If Sam Altman acts differently in the world where profits are on the horizon, that information leaks prematurely. Thus, he has to act as if OpenAI is strapped for cash, whether or not it is.

This reads similar to the Trump 4D chess excuse. It seems unlikely that this is a ruse, and much more likely that OpenAI's market cap is supported by doing "all the things" to exploit the huge monthly average user base that OpenAI has accumulated.
I would just assume that they were still spending VC money to lock in users if nothing happened. I would not assume "AI is about to make money obsolete"
