If that worked, then there would be an epidemic of phone scammers or email phishers having epiphanies and changing careers when their victims reply with (well deserved) angry screeds.
This is the level of response these PRs deserve. What people shouldn't be doing is treating these as good-faith requests and trying to provide feedback or asking them to refactor, like they're mentoring a junior dev. It'll just fall on deaf ears.
This is maturation, open source being professional is a good sign for the future
edit; and just to be totally clear this isn't an anti-AI statement. You can still make valid, even good PRs with AI. Mitchell just posted about using AI himself recently[1]. This is about AI making it easy for people to spam low-quality slop in what is essentially a DoS attack on maintainers' attention.
That means you, like John Henry, are competing against a machine at the thing that machine was designed to do.
