The most memorable clip I've seen of him was the Brad Gerstner's podcast one (an investor of OpenAI), Gerstner questioned Altman about the financials of OAI, how could it have committed to spend so much given the revenue, it's a decent question and it's been up in the air for a while across the media.

Altman's reaction was very telling of the kind of person he is, just immediately lashing out at Gerstner in a childish way, asking if Gerstner wanted to sell his shares because he could find a buyer in no time.

It was a pathetically immature reaction, I wouldn't expect that from any kind of professional, even less someone who has held positions as Altman has and now sits at the top of the leadership for a company sucking hundreds of billions of investment.

Apart from that clip there's also the whole saga of sama @ Reddit, full of lies, deceptions, and the same kind of immature attitude peppered across Reddit itself.
