It's the only bit of the response that I don't agree with. I don't come to HN solely for utilitarian purposes. If I think I'm frequently communicating with a machine on HN then then I'll stop going to HN. It really will kill HN for me. If I want to communicate with a machine for utilitarian purposes then I'll go directly to the machine and I will know that I'm communicating with a machine (a machine that cannot bring me any new experience from the real world that was not mediated in text. A machine that can only select that text on a statistical basis. A machine that was in part trained on my own words from the past!).
