No, I doubt it!
git/GitHub can be painful for everyone... it takes a long time to master. (And probably extra trouble with Unity? Maybe we should schedule a 1-on-1 screen-sharing to take a look at your GitHub situation...)
Furthermore, a computer science major is a good choice of major even if you decide that you don't want to go into software development for a career. It's good preparation for a career in I.T., or database administration, or (I would argue) even careers that are further afield, like becoming a politician, a lawyer, an entrepreneur, or a marketing consultant.
