I have three CS degrees. Our field has a real problem with hubris and reinterpreting everything through a CS lens, particularly assuming everything is discrete, falls into neat categories, and is not subject to noise.

I had a decade long debate with a friend from Chemical Engineering about whether the Universe was continuous or discrete, and also about whether it was deterministic. I recall confidently stating tons of crap about quantum mechanics, and it turns out I was completely full of shit because I did not understand probability theory or wave functions.
