Interesting that they boo'ed him considering he is one of the only tech billionares acknowledging that AI is both a blessing and a curse.
Look at the likes of Elon Musk, he does zero philanthropy in comparison to anyone and works people to the bone like they are dog food.
At least Bill Gates and Eric Schmidt actually have good reputations from the people they work with.
I suggest that they booed because we are all sick of hearing about AI. Everyone knows it is the future, apparently. But they never stop telling us.
