Even before the internet, a determined person could learn about anything at a library. It's been a long time since a university has been strictly necessary for that. Today, at least at the undergrad level, universities function as a job screen for people who can dedicate themselves to an academic program and complete it, providing practical experiences in labs, internships, and clinical settings that an individual cannot really do for himself, and also for meeting people and starting to build a network.
