The university experience is whatever people choose to make of it. The people who complain most loudly about how college was a waste for them tend to be people who took no initiative of their own and expected to simply be spit out of some pipeline of courses into a top tier job. OP is clearly not one of those people, and has an internally driven passion for learning, pursued of their volition. That doesn't mean OP is somehow beyond college, it means they are an excelent candidate for it.

The combination of breadth and depth of knowledge and experience available at universities is unmatched anywhere in the world. OP may find themselves more interested in developing neural interfaces, working on processor hardware architectures, designing next generation microscopy systems for biology, or a hundred other things. It's true that there are other entry points into those areas that don't involve being on a campus, but a good university provides efficient entry points into all of them. This is especially true for students who set up independent study courses for themselves, start/run student organizations, talk to professors about their research, and seek out research and project opportunities during summers.
