Many people in this and other threads around this topic have already stated what they are going to do, which is the inevitable conclusion: move to private chats/discords. I’m sure some amount will remain on IRC or maybe IRC will get a second wind (unlikely). Websites like HN will have to make a choice going forward because now they’re on a trajectory to complete enshittification. Your handle and karma doesn’t matter if the site is dominated by bots. It’s basically a hollow shell of what it used to be and there’s no value to it at a certain point. You’ll be replying to bots more than humans.
There’s plenty left to discuss for humans. But LLMs don’t discuss.
