Good point. The counter-quote could easily be something like "Why do most Nobel Prize winners do their prize winning work in their mid/late 30s? I don't know. Older people have more experience. They prioritize. They have families. Having more responsibilities forces you to be more efficient."

But I won't knock Zuckerberg for being young and naive once. I was too. Hopefully he's growing up a bit and realizing that there is a lot more to success than founder age.
