And if you never do, even after fifteen years working dozens of different project? Including a few projects that have run for most of those fifteen years?

I agree that git is weak for binaries, but the only binaries I need to keep in it are a few images and installer - nothing that has many versions, nothing that causes me problems. Similarly, a lot of open source software is mostly made up of code, not blobs.

As for distributed work, even when I'm the only developer on a project, it helps not to have to worry about a central server, especially if I'm on-site. It's also hugely faster than SVN ever was.
