I'll be the first to admit that university is bullshit and mostly acts as a social signifier. Like I mentioned above, I'm credentialed, and I'll put that on my business cards but between you and me and the internet at large I mostly work as a software engineer.
There are even many problems with talking about "computer science" because for the most part it's treated like a branch of mathematics and its academic circle really hates dabbling in messy empirical data.
Yet, there's a degree of rigour in it. There's an actual underpinning behind a lot of this stuff.
So! Can you be a self taught computer scientist? Certainly! K&R and The Little Schemer just have almost nothing to do with it - even if they might make you into better programmers :).
