It's tempting to dismiss the experience gained at college as being not useful or applicable, but from my experience, there is generally a noticeable difference between those who learned all the fundamentals (e.g. college level math, physics, language theory), and those who are self taught.
There are alot of really talented self-taught coders out there, but for the rest of us, the breadth of understanding from slogging through those boring lectures on BNF, multi variable calculus, and linear algebra gave us an incredible analytical base thats easy to assume we always had.
