In the more theory-oriented departments this is possible. It's easy to assume that the parts of CS you understand well are the important parts. It's the converse of the Blub Paradox. Might there be things that other people consider fundamental that you're only passingly familiar with? At the meta-level: contempt (like that you're expressing) is a bit risky: it can be hard to tell whether it's motivated by a desire to uphold high standards, or the need for a quick bump to the self-esteem from putting someone else down. If it comes too easily or too often, I'd worry it might be the latter. I was present at the keynote.
