> 3. I spend a week with creating a test language with a different trade-off for multiple-inheritance. Then I ask an LLM to summarize the unique features of the language into a couple of paragraphs, and then I post that into HN

I think where you are getting hung up is the idea of "better results". We as a community don't need to strive for "better results" we can easily say, hey we just want HN to be between people, if you have the LLM generate this hypothetical test, just tell people in your own words. Maybe forcing yourself to go through that exercise is better in the long run for your own understanding.

My example was not great.

But my point is that I read HN partly because people here are insightful in a way I can't get in other places. If LLMs turn out to ultimately be just as insightful, then my incentive to read HN is reduced to just, "read what other people like me are thinking." That's not nothing, but I can get that by just talking with my friends.

Unless, of course, we could get human+LLM insightfulness in HN and then I'd get the best of both worlds.

If someone can't explain something in their own words, then they don't _really_ understand it. The process of taking time to think through a topic and check one's understanding, even if only for oneself and the rubber duck, will reveal mistakes or points of confusion.
