If you're saying that no generation invents culture completely anew, sure, that's undeniable. And uninteresting.
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.
