This is slop, in the sense that it looks like a lot of useful work and effort, and AI is heavily involved, and it was offered up when the opposite was requested, meaning it's not at all helpful in this context.

I raised this in a harsh, but repeatedly apologetic way. The person then responded telling me to "get my facts straight" and doubled down with more weak, qualitative outputs of LLMs.

I don't assume the person is incompetent because they used LLMs. I use them daily. I'm a firm believer everyone is an idiot, just in a different subject.

The issue here I feel is that LLMs are increasingly leading people think that they're not an idiot in any subject at all, and when real humans question it, they double down with more AI stuff.
