There are teams where people are having more fun 'kicking ass' and getting things done, and have a great time with the people they are there doing it with, and frankly they would laugh you out of the building (literally) if you even for one second referred to them as 'resources'. I have seen people wander into the office on the weekend just because they were bored (including myself), or were looking to hang out and hack on some stuff. It's not something that burns you out, it's a passion for some people. The good people.

I think you have had a very limited (and limiting) work experience, to be honest.
