A better question is why anyone should bother to take their time to read something that's not worth yours to write. This goes for most of AI output, honestly.
You can apply this logic to procedurally generated games like No Man's Sky. Why would you want to play a level that a human didn't even bother to design?
I'm not sure I would go whole-hog and let this tool rewrite my history but my `git commit -v` wraper pre-populates the commit message with something AI generated based on the diff and I've been quite happy with the results. I think my commit messages are much better as a result.
