alt Hacker News> people are demonstrating a new behavior that is disrupting social norms
The social norm has always been that you write comments on the internet for yourself, not others. Nothing really changes if you now find enjoyment in adding AI output to your work. Whatever floats your boat, as they say.
The issue isn't people posting AI generated comments on the Internet as a whole, it's whether it should be allowed in this space. Part of the reason I come to HN is the quality of comments are pretty good relative to other places online. I think it's a legitimate question whether AI comments would help or hinder discussion here.
