There's a super-viral post going around on here with replies and quotes disabled that is just a rip-off of someone else's image from more than a decade ago. See old.reddit.com/r/mildlyinte... for what *might* be the original source but it's hard to say.

How is it that some people in the US just lose their shit entirely just by being exposed to a "foreign" language? Weird sheltered lives.

Yup this is what drives me crazy in vibe coded PR.
I'm used to trying to provide feedback to help contributors, especially beginners, in the long term, but when it turns out it's just a coding agent interface in a disguise and not a human learning from mistakes... it's difficult to stay motivated.

So what will they do? They will blindly feed your review comments straight to their agentic coding model because that's the only thing they know how to do.
By doing so the vibe coder has put the maintainer in the weird position where the maintainer is doing agentic coding through a shitty UX

Why has Trump's year of negotiations been the deadliest for civilians in Ukraine since the full-scale invasion? The number of deaths and injuries has increased by 31 percent compared to the previous year.
