One thing worth saying here is that Git is now the dominant player in the source control market. According to almost every survey I've seen, it's overtaken Subversion (according to some reports by a fairly large margin) not only for open source and hobbyists but in the enterprise as well. It's more or less become a lingua franca for communicating source code between teams these days, as well as being the preferred deployment option for many cloud hosting providers and even some package managers. No other source control system has ever managed that. As such, you simply can't afford not to know it these days. In fact, I can't help thinking that not using Git should now be a major red flag for job candidates and prospective employers alike. Sure, not using your favourite tool may not be that big a deal, but not using what is to all intents and purposes the lingua franca of source code communication is a serious omission.
