Sometimes I feel like that. I mean, after all, I am working my day job to make money as a first priority, in order to take care of myself and my life. If I were able to do what I wanted purely without a need to make money I probably wouldn't be working where I am. That's not to say it isn't often fun and engaging to work on iOS, web, and business development with a team of people who are great at it. The developers on the team all seem interested in learning more, like you, and I don't get blank stares when I mention github, but I used to get blank stares when I talked about things like the Earth's environment, physics, and the way that the world works. Gradually, with patient persistence over a few years, as I shared some good problems of why it is important through whatever appropriate opportunity it was, they began to realize. Now I don't get only blank stares and mocking smalltalk, but there are some questions that they ask me about them and I can show them things through the questions they have.

Anyway, we are a small development firm that works with design partners and other clients, we build software for them, and we have a CMS platform that we tailor to their needs too. This is a big reason why the environment at my office is different than yours (we have a team of about 8 right now). Each person has to pull his weight for things to turn out well and we each recognize it, so many of us try to get to the level of expert in our own specialties. If expertise is recognized or rewarded then it provides an incentive to for self cultivation.

If you don't mind me asking, what is the specific area of software development your group works in?
