I don't agree with that. I have more than half a dozen friends who are software programmers, and they have even more friends that they know through their jobs and I'm here to tell you that most of them are smokin hot! They are just so focused on their work and like you say, sometimes they are camouflaged a little too well and you end up missing them altogether.0 to none.
But it depends; many girls are hot but camouflage when it comes to work and career.
