He is just being solipsistic and talking to a small circle of wealthy and well-connected Gen Zs that he probably knows in real life or who are part of his acquaintances. Or do you really think that people with his level of wealth remotely care about real career paths for the average youth?
I don't know anybody with Hoffman's level of wealth, but I have come across a fair number of people with close to a billion dollars of wealth that now split their time between enjoying time with their own family and then trying to pursue philanthropy and non-profits meant to improve everybody's life in the community.
I run into them because of their attempts to improve the community. And there are those who do it super quietly, give big, and do everything they can to avoid getting credit for it; there's another Silicon Valley Reed that does this in my community. Steve Jobs apparently did this too, big donations but anonymously.
Do not take the blabbering idiots on the All-In podcast as representative of all of Silicon Valley, the old Valley was far different than those people and there are still plenty of people that pursue wealth not for the purposes of their own self-aggrandizement and power.
