Git is an example how a technically inferior tool can still dominate. No offense, Linus: Git is great. But other DVCS exist, such as Mercurial SCM. Jujutsu has recently been the subject of much discussion. Given that 20 years ago, we worked with Subversion (SVN), I wonder what will be the state of the art tool in 20 years.

Happy birthday, Git! I like you despite your weakmesses. Or is it only my weaknesses? I don't know, I'm drunk right now.
