On the other side of the coin, I am not really an engineer and have worked mostly in project management or marketing, working with engineers. And I have to say, this type of thought is why everyone tended to avoid dealing with engineers as much as possible.
There is quite often this mindset of superiority amongst the engineering community and it only serves to isolate them further. Engineers aren't all knowing, and everyone else aren't brainless morons. While engineers might know engineering, the marketers know marketing, the salesman know sales, the financiers know financing and so on. It takes great collaboration among everyone to make a truly great product and to have it really make an impact.
So, please, if you can, avoid this "surrounded by idiots" type of thinking. Everyone is working towards a common goal, and the sooner we realize that we aren't better than anyone else, the sooner we can achieve our goals.
