While most of the core commands and concepts are still valid today as the Git core team is pretty fantastic at keeping things backward compatible, there have who introduced an issue and when, and more. Using a VCS also generally means that if you screw things up or lose files, you can easily recover. In addition, you get all this for very little overhead
