However, there seems to be a decent amount of evidence that Sam has done exactly what you're talking about.
He manipulated and was "not consistently candid" with the board, he got all the OpenAI employees to support him in his power struggles, he made them afraid to stand up to him (https://x.com/tobyordoxford/status/1727631406178672993?s=20), he exhibited delusions (though I guess they were correct) of grandeur with pg with a glint in his eye making clear to pg that he wanted to take over yc, he did little things like made it seem that he was cool with Eliezer Yudkowsky with a photo op but didn't really chat with him, etc.
Again, I am not sure this perspective is necessarily right (and I may be convinced just because he's such an effective psychopath).
In any case, I think this is a pretty good explanation of this perspective: https://x.com/erikphoel/status/1731703696197599537?s=20
Elon Musk actually matches several of those poorly, and matches bipolar disorder much better (most of those are also bipolar or billionaire symptoms, while psychopathy is inconsistent with many Musk symptoms like catatonia): https://gwern.net/note/musk
Psychopathy is a personality disorder indicated by a pattern of lying, cunning, manipulating, glibness, exploiting, heedlessness, arrogance, delusions of grandeur, sexual promiscuity, low self-control, disregard for morality, lack of acceptance of responsibility, callousness, and lack of empathy and remorse.
(Which, now I read it, is disappointingly pattern matching the billionaire who invested in both OpenAI and also a BCI startup currently looking for human test subjects).
I can see arguments for either saying Altman has delusions of grandeur or lack of acceptance of responsibility depending on if you believe OpenAI is going too fast or if it's slowing things down unnecessarily, but they can't both be true at the same time.
