Zuckerberg said he supported UBI because he recognized that he was only able to start a business because he grew up well-off enough to know that he wouldn't starve if the business failed.

But... I always like to think of the Taleb quote: "Don't tell me what you think, tell me what you have in your portfolio"

So, still waiting (unlike Elon Musk and Sam Altman who have both come out in support of Yang right now)
