That really depends. If you're just trying to get trained for a vocation, then yeah, you don't need 4 years. However, I do think a 4-year degree is a unique opportunity, and it shouldn't be seen as a screen for people who can slog so much as a fit question of "do you need the other things that come with a 4-year degree?" I'd guess that a bit less than half of my 4 years was spent on academics, of which it was 2/3 CS degree and 1/3 liberal arts. The rest was summer internships, hobbies, personal projects, engineering teams, research, and just playing around as an 18-22 year old. I agree with the parent poster's advice though. Outside of my academics, I learned skills like writing, speaking, organizing, diplomacy, etc. which you often learn anyway through work experience. People returning to school need that much less than people who never worked do, so there's no need for them to pay the time tax on extracurriculars. |
I've found that every major personal change I've gone through - college, entering a career, moving cross-country, working at Google, being an entrepreneur, and even my relationship with my wife - took about 4-5 years before I was really comfortable on a gut level with my new life and could accept it as part of my identity. The actual technical material takes much less time to master - I found I was pretty competent at Javascript after 6 months, I could make major changes to Google at a year, I knew where most of the important things in the Bay Area were within a year, etc. But that's not really the point. The point is that when you go about your daily life, without thinking too much, have you internalized the value system and worldview that you're being educated into? It's the transition into unconscious competence.
Now, whether the university system teaches a worldview that correlates well with what you need for success in the rest of the world is another question. Just a couple months ago, the President of the U.S. was tweetstorming about academic brainwashing in universities. And depending how you squint, that may even be accurate - a worldview looks like brainwashing to people outside of that worldview. But the fact is that the vast majority of people in positions of wealth and power have been through those 4 years and have adopted that worldview, and doing so yourself will significantly reduce the friction as you interact with them.
