They're almost invariably low quality and deserving of downvotes for that reason, but being open is better than them being camouflaged.
Most such comments are actually informative, and the honesty about asking an AI is an important detail. This particular one was heavily downvoted, as it should have been, because it was wrong. It was still a human writing, trying to be helpful.
However, you should downvote for doing things that hurt the community -- and "I asked ChatGPT" hurts the community almost as much as "I googled this for you" does.
It's fine to downvote things that you believe are wrong or simply disagree with, and I have read mods on HN say that downvoting for disagreement is okay. Asking or insisting for more from an HN user is presumptuous, and discussion of voting is largely considered off-topic and therefore not really what the guidelines suggests we should do.

> Downvoting for disagreement has always been fine on HN. People sometimes assume otherwise because they're implicitly porting the rules from a larger site, but that's a mistake.

More to the upthread point, generated comments are against guidelines:

> HN has never allowed bots or generated comments. If we have to, we'll add that explicitly to https://news.ycombinator.com/newsguidelines.html, but I'd say it already follows from the rules that are in there. We don't want canned responses from humans either!
These are quotes from dang, not my own. I'm just a HN user, which is why I found the quotes to help everyone make up their own mind what the guidelines say.
The character of a community is formed by what it does more than what it says it does.

The whole comment is worth a read, so here’s just a taste:
> Our goal is to optimize HN for intellectual curiosity, which requires a higher signal/noise ratio. Downvotes dampen low-value comments. I know downvotes do bad things too, but that's the good thing they do, and it's big. Taking that away and/or increasing the noise with a flood of people disagreeing about their disagreements would not be an optimization.
