A lot of my development experience is actually about handling people. Both management and other developers. Ego is indeed a big problem. I wish my job would be just programming/designing/debugging/testing, but this is not the nature of most of the jobs. Instead it is managing expectations, estimations, negotiating specs, features, explaining what is realistic, what is not, what is possible and what is not and why. It gets tiring quickly and is also thankless as often arrogant people who aren't actually helpful or working in the best interest of the company get mistaken for rock stars and get to do even more damage you need to fix. You also need to deal with that from time to time.
