When someone says: "Source?", is that kinda the same thing?
Like, I'm just going to google the thing the person is asking for, same as they can.
Should asking for sources be banned too?
Personally, I think not. HN is better, I feel, when people can challenge the assertions of others and ask for the proof, even though that proof is easy enough to find for all parties.
IMO, HN commenters used to at least police themselves more and provide sources in their comments when making claims. It was what used to separate HN and Reddit for me when it came to response quality.
But yes it is rude to just respond "source?" unless they are making some wild batshit claims.
But: Just because it's easy doesn't mean you're allowed to be lazy. You need to check all the sources, not just the ones that happen to agree with your view. Sometimes the ones that disagree are more interesting! And at least you can have a bit of drama yelling at your screen at how dumb they obviously are. Formulating why they are dumb, now there's the challenge - and the intellectual honesty.
But yeah, using LLMs to help with actually doing the research? Totally a thing.
