On the other side, people who were using, say, Perforce, also thought there can't be anything better. Still, BitKeeper appeared as an innovation in the area, eaten later by Git, created by angry Linus (because of BitKeeper licencing changes).

So, even though Git seems to be ok (people who store large binary files or who run huge monorepos would probably disagree), maybe we can do better.

Altavista was kind of okeish for search, yet Google managed to figure out something that was (at that time) way better.
