And I'm pretty sure this "29-30 year old who was merely acquihired" probably knows more than these veteran/boomer execs about how to execute a consumer AI product strategy.

"Chief AI officer" does not mean he leads AI research efforts, its just a title. He just takes care of hiring and product direction, both of which I'd say hes done well in. They obviously have actual researchers working on models.

I'd go as far as to say Alexandr Wang can do this better than most other leaders. Young people should be in charge of products, they generally have a better sense of what resonates with consumers, and Meta is a consumer company at the end of the day.
