I used to think when I first started my company that I could just do every part of it far better than anyone else. I would push on my employees pretty hard and often denigrate their efforts. As the company is continued to grow, I now have 180 full-time employees. The reason I have all these people is that they can do enormously more work than I can and most of them are now better at doing their individual job than I am.

I think your comment visits are tendency as tech people to view ourselves in the best possible light, and to view other people as not as good. We especially tend to view projects we do as big and very complex and project done by others as not impressive.
