I disagree. The quality of ChatGPT output isn't likely to be worse than the average HN comment, rather it's likely to be better as it doesn't contain outrage, bias and bad faith interpretation, nor would it likely violate site guidelines. ChatGPT could likely simulate the bulk of many repetitive conversations by pre-submitting the typical pattern of common responses to a thread, which would make the forum far more efficient in that it's no longer necessary for a human being to involve themselves in such performative tedium.

Far from being banned, I think ChatGPT should be integrated into HN and given mod privileges. Not only should it be used to generate high quality conversations, it should be able to detect and downvote low-quality human generated content. Eventually, we could dispense with human comments altogether.
