My feeling of why it's going down is, it's no longer run by people that are capable of building AI. Look at the leadership faces of openai. Who among them has any substance to build a AI? One is a business dude(good one) and another a product manager. Where are the techies?
Sam altman- a buisiness guy through n through. Required but not sufficient. He is strong in his strengths.
Mira- just a pure bred product person with 0 technical background.. how will she command scientists or engineering trust and respect?
Greg was the last technical leader in this technical marvel of a company. After Ilya left its all wolves mooching on a good thing...
