learning about different version control systems. For example, the differences between Fossil and git revealed a lot of my biases towards git simply because it’s familiar (and Fossil seems really cool). Reading about the theory behind Pijul absolutely bends my brain into knots. I keep trying anyway because conflicts in git are frustrating and I’d like a better solution.

It would be nice to move beyond git one day and have a better experience for managing complex codebases, and not on GitHub’s timeline.
