It's very easy to fall into the trap of believing this: git's implementation fits together neatly enough that it feels like the best you could do. Like, yes it's complex, but surely that's just intrinsic complexity of the problem? (Also, I think we all sometimes feel like someone with a different view must just not know as much as us.)

But if you have used other version control systems (I'm thinking particularly Mercurial here) you realise that actually some of that complexity is just totally made up by git.
