Git turns 20: A Q&A with Linus Torvalds - The GitHub Blog

Git’s unconventional and decentralized design—nowadays ubiquitous and seemingly obvious—was revolutionary at the time,

Of course, there's more innovation in git than being DVC but the decentralized nature wasn't revolutionary.

It was funny when I started using bzr and then git, I kept being told "it's a DVC, which is a different way to work that takes some getting used to", and I was puzzled as it felt very familiar to me. Then I looked up DVCs and found out that Sun's Teamware that I'd used for a decade was also a DVC. It was actually a return to familiar and comfortable workflows after a brief period using abominations like Perforce and Clearcase. I'm so glad they've been largely replaced. Git may not be perfect, but it's better than those in any use cases I have had.
