> All of this is now provided with superior quality by the internet. Now the only advantage of a university is signaling where you got accepted, networking with similar people for future jobs, becoming socialized by a culture of university-types, and showing you have the discipline to jump through 4 years of fairly arbitrary hoops. There is value to this, but is it worth $200k+?
You are leaving out some of the main benefits of going to a university. Specifically, that you have people to guide you through the process of learning; to point out the things that are important to learn, to be able to talk to them about the topics, etc. The internet has a lot of useful information, but there are things you don't get from it. Just like you don't master the English language by owning a dictionary.
