There is a lot of truth in this. The common argument for word is "track changes is good", but it actually sucks in many ways: try doing a three-way merge, for example (from co-authors A, B and C) or a diff. TeX can use all of the power of modern editors and this sort of thing just happens really nicely; with git it happens seamlessly. I think another big problem is that Word is one monolithic thing that aims to do everything, and in reality does nothing well.
