But I can see why the HN guideline is formulated that way. My students often use the excuse "I did not use AI for writing! I wrote it myself! I only used AI to translate it!" Simply disallowing all kinds of AI usage is much easier than discussing for the thousandth time whether the student actually understands what they have written.
Like, there is this computer game, authors used some models or something like that, generated by AI, but it was only used during prototyping and later it was replaced by proper models. No one would know about that, if authors would not tell about it. So, if someone writes in their own words what AI generated for him, is it still argument made by human or by AI? What if someone uses AI only as placeholder and replaces all that content, so you never actually see actual AI usage, but it was used in the process?
For me, premise that using AI in any form invalidates your work, starts with logical fallacy, so such arguments against using AI are weak. It's like saying that your work is wrong, because you used calculator, so your calculations can't be right, if done by machine, because it had to make mistake or that's wrong for ethical reasons or whatever.
Work generated by AI can be easily poor, because these models make mistakes and like to repeat in certain ways, but is it wrong that I'm writing comment with keyboard, instead of writing letters with pen? Is it wrong, when I use IDE or some CLI to write code with AI, instead of using vim and typing everything on my own? Is it wrong that someone uses spell-checking?
In the end it doesn't matter who seems smarter, when you're expected to use AI at work. Reality shows you actual expectations.
Anyway, my university did not ban AI, and now most students have degraded to proxies between teaching assistants and ChatGPT.
At certain point it's no longer about AI specifically, but about power and showing who makes decisions.
I agree that there might be some threshold for obvious spam, but if you're making argument in good faith and you don't claim to have authority on some matter, there will be always people that think differently or disagree with you, because they have different interpretation or they need better sources, more evidence. It's actually typical, because different people use different perspectives, different assumptions, different tools. I don't believe that rules should be used to silence people that have different opinions and that's the biggest risk I see, because penalty for not following such rules, which are hard to measure correctly, creates power imbalance.
At some points it becomes dogma, not fair debate and not everyone likes to stick to dogma and it's hard to do creative or innovative work, if your work has to meet strict, but subjective, possibly incomplete criteria, to be considered valid work at all.
