I think "necessary" needs clarification here. What you intend or expect to be able to do or understand dictates what's necessary or sufficient. There is no necessity for an education when your goal is simply to feed yourself; many menial jobs that are entirely within the grasp of people who have no formal training or education will satisfy this need. In more of an HN demographic context... I'm in the "socialization" camp. College/university can serve a similar purpose as attending primary and secondary schooling, i.e. to further develop your social skills with other people as you age. While this can be found in other places, I'm not sure how effective it can be for those of us who wouldn't otherwise go out of their way to interact with others. In the vein of preparing you to do specific, non-obvious things, I would agree with you that education is necessary; I do think we should get out of the "high school -> college -> job" idea that seems to have turned into a fallacy over the last decade or two. Trade schools can be a good example of this; in my opinion, apprenticeship is also a great alternative, though in the US those are -- as far as I know -- almost nonexistent.
