A thousand times yes. I've met tons of good programmers, even CS/CE Ph.Ds for whom networks and anything wire-releated is black magic beyond mortal understanding. Not only does it prevent them from dealing with or writing such systems, but it's also a major contributor to clueless security FUD. It's not that there's nothing to be afraid of... it's that if you don't understand how networks work you are probably afraid of the wrong things.
