See the sibling comment from AlexandrB. Altman and tons of other hype men in tech do this thing where they make outrageous promises, then retcon as “just jokes” whichever ones don’t come true, so that they can never be disproven. It’s a swindle made all the more irritating by the enablers like you who go “why did you take the joke seriously?” to get cred on the internet while helping the scam continue.
Or to put it another way, do you think Altman denounced all the hype (and subsequent investment dollars) he got because of the “AGI achieved internally” post? Did he say to anyone “hey, that was a meme post, don’t take it seriously”? Or did he milk it for all it was worth before only later quietly climbing down from that when it was no longer paying dividends. Again, duplicitous and disingenuous behavior.
