I doubt git will be used half a century from now: * Heuristic textual diffing is probably inferior to recorded actual diffs from our code editors * Git merges are monolithic, and hide conflict resolution work within them in a difficult-to-review way. On the other hand, git cherry-picks do not track history properly. Future revision control will probably solve this problem better (e.g: darcs seems like it should work better, except darcs has some other [probably more important] disadvantages).
