This is probably a good rant for some other topic. But Zuckerberg is only 30, even now. The people I see turning up at entrepreneurship events and in the fundraising news aren't 60. They're ~25.
Zuckerberg himself played the tech tune sung by greybeards before him--LAMP was not invented by millenials. LAMP was not popularized by millenials. Zuckerberg's Facebook was a LAMP project.
Of course people showing up at newbie events are newbies!
The people pulling the strings sit in boardrooms, academic boards, they have office hours, people come to them!
But there's a big difference between somebody choosing to do what's known to work and that person being forced to do something that doesn't work because other people have the power. Zuckerberg started in the LAMP stack because that's what he liked for his pet projects, not because some mean old Stanford greybeard forced it upon him.
I never said greybeards are "mean", I said they are influential. Greybeards are more influential on Zuck than vice versa when it comes to technology choice. That's why Zuck chose greybeard certified tech to erect facebook on.
