First, that's just wrong.

"Geeks", as a class, will tend to focus on technical issues before aesthetic ones. Looking at that fact and immediately equating it to an absurd extreme is a fun game, if you don't care about describing reality. I know some accomplished engineers who are also good designers, and vice-versa.

Second, if my professional opinions are not being taken seriously, that usually means one of two things: I'm too far out over my skis, or am in the wrong place with the wrong people. Especially so if you feel like a chef making burgers.

Of course, if "in total control" and "irrelevant" are the only two states of being one sees, I suppose I see how you get there.
