I can't tell if you mean "eventually they graduate and carry the new ideas into the world" or if you mean "eventually they graduate and buy into into the system and turn into drones like the greasers, hippies, and punks all did."
And it's not like we haven't seen the same pattern before with the Weather Underground. (I do feel obligated to acknowledge that I was one of those people on the "just in the universities" train 5 years ago, so I'm not accusing anyone of a mistake I haven't made myself.)
The Weather Underground was founded by students from the University of Michigan, who spent their college years arguing that people should violently resist the government. When they graduated, they didn't moderate out of these ideas; they doubled down, started an organized bombing campaign, and successfully hit targets including Capitol Hill and the Pentagon.
