A few times a week I’m finding open source projects that either have a bunch of old issues and pull requests, or unfinished todos/roadmaps, and just blasting through all of that and leaving a PR for the maintainer while I use the fork. All tested, all clean best practice style code.
Don’t complain about the outputs of these tools, use the tools to produce good outputs.
I’ve had a similar experience to what you’re describing. We are slower with AI… for now. Lean into it. Exploit the fact that you can now iterate much faster. Solve smaller problems. Solve them completely. Move on.
