This isn't just "making mistakes." It's so profoundly obnoxious that I can't imagine what you've actually been doing during your apparently 30 years of experience as a software developer, such that you somehow didn't understand, or don't, why submitting these PRs is completely unacceptable.

The breezy "challenge me on this" and "it's just a proof of concept" remarks are infuriating. Pull requests are not conversation starters. They aren't for promoting something you think people should think about. The self-absorption and self-indulgence beggar belief.

Your homepage repeatedly says you're open to work and want someone to hire you. I can't imagine anybody looking at those PRs or your behavior in the discussions and concluding that you'd be a good addition to a team.

The cluelessness is mind-boggling.

It's so bad that I'm inclined to wonder whether you really are human -- or whether you're someone's stealthy, dishonest LLM experiment.
