Well what kind of college? Hardware engineering? Cyber security? At most traditional colleges (either "liberal arts" or "institutes of technology"), you don't really get that specific, at least not via coursework. The closest thing you'd get to hardware engineering is electrical engineering, the closest thing to cyber security would be computer science or math, and you won't be learning anything about the specifics of anything, but instead very basic (doesn't mean its easy) things.
As far as I can tell, there are two extremes of people: academics, and non-academics. Non-academics see college as something needed to get a job, so in general it doesn't matter to them what they learn or don't learn in college. Academics are genuinely interested in the subjects and hence enjoy studying them for the sake of studying them (I'm not saying this is a good thing, at some point you might realize doing that is pointless).
I feel like everyone is on this path where you like school up to the point where you give up on it, and decide to make a living/do something real. Everyone reaches this point at some point. Some people leave as early as high school. Most people leave after college. A minority after a grad degree, etc. Some never leave.
Traditional college is not career training, per se. You go there to open your mind.
Vocational school, on the other hand, is training specifically so you can find a job.
The main thing I learned from college is that I'm not too smart and barely know anything about anything, and that everything worht learning about has a level of sophistication you hardly imagine. You can choose to keep pursuing it, trying to "understand" it until you give up or become a professor, or choose to not deal with it, enter a job, and instead deal with non-intellectual challenges.
I guess I don't even know what I'm saying anymore. I used to write a lot better before I went to college.
