Why do these people even go to uni when its such a waste of time. I went to uni for a year and learned absolutely nothing because it was all so incredibly basic that its only useful if you don't know how to learn on your own.
The most annoying type of people in CS studies I encountered were those who thought they "knew it all" yet in fact, in the large scale, they knew very little. And whatever knowledge they had they often communicated poorly, perhaps disparaging others for not knowing what they did.
