I think you're probably right that the article was AI-assisted, but (if so) it's important not to confuse that with the thing the article is about. Google wouldn't pay $90k for a hallucination.
I don't mean that as a criticism—the question of how to receive AI-processed content is chaotic right now. I'm working on a post about that here: https://news.ycombinator.com/item?id=48887149.
Btw, Nebula Sec is a YC startup in the current batch. We've been working with them on how to launch on HN, and one of the things I've been trying to explain is that the HN audience won't respond well to LLM-generated reports. The underlying work, though, is impressive. These guys know what they're doing—the OP is by no means their only significant find—and the fact that they're doing it with an agent, rather than the traditional way, is significant.
You should put a note in Find a Cofounder not to do that as well. Huge turnoff for me, though I guess a great filter.
A thing that notably triggers my allergies is that if significant human effort went into something, a few paragraphs written by a human seems like a trivial additional investment; if that last touch is missing, it's really hard for me to extend the benefit of the doubt that there really is something there.
Obviously this is only one signal among many, one that can be overruled, but the ick remains regardless.
