There's no danger of me dropping Git, the best alternative I've seen is Fossil and (opinion me) I think Fossil makes more mistakes than Git does. But Git definitely still has flaws; a lot of this post rings true to me.
I do think that Git gets a lot better the more that you understand how it works. Not perfect, a lot of the flaws being pointed out here are core flaws with Git's internals and have nothing to do with the UI. But it does get significantly better; some of the failure modes are much easier to avoid if you've spent time digging into how Git works, and the whole thing starts to feel a lot more elegant the more that the abstractions are stripped away. But that's also kind of a flaw in itself: Git's user interface is much more complicated than the underlying program or concepts are, which is obviously not great.
