Haven't really paid attention to Altman, so can't comment there, but on the Musk file I will say it is insane that anyone relies upon his future benevolence. And they do rely upon it given that America is 100% a plutocracy now and is run in the service of the ultra-rich who hold complete and utter control over government.

Musk's entire history on this planet betrays him to be a profoundly selfish individual with perilously little regard for anyone else. Musk and his ilk (Trump, Bezos, Page, Ellison, Thiel, etc) are more likely to see you ground up into Soylent Green than to offer largess like UBI.
