It’s not irreplacable. But it’s very well put together, and a great ecosystem of tooling exists around it. So any potential replacement would have to be a lot better for people to move. And for those of us that remember the dark days of CVS and the pain of migration (I helped migrate drupal.org from CVS to Git), that is a good thing. I don’t miss the days where you had to make difficult SCM choices when starting a new project, whether bzr, Mercural or Git was the right choice. Git has become the lingua franca of SCM, and that is great. So many great developer tools exist that integrate seamlessly because it is safe to assume that 99% of the audience for it will be using Git.
