When I learned about git bisect I thought it was a little uppity. I thought it was something I would never use in a practical scenario. Working on large code bases. However, sometimes a bug pops up and we don't know when it started. We use git bisect not place blame on a person, but to try to figure out when the bug was no longer there so we know what code introduced it. Yes, clean code helps. Sometimes git bisect is really nice to have.
