I feel bad for people who believe that age beats talent.
There is a big tendency for young, talented devs to assume they are the smartest person and/or the best coder in the room because up until now they've always been (even in college), but at some point in their progression that stops being true. I'll even go so far as to suggest that if you are still the best coder in the room you should probably go out and find a better room.
