> It's too well structured and the message is too clean. HN (and the whole internet) is allergic to proper writing. We praise human sloppiness now.

Yes. And it's only a matter of time that the model companies start to try to train in that "human sloppiness." After all, a lot of their customers want machines that can pass for humans.

> No, I'm not being sarcastic. People have given up em-dash, which is an official punctuation you use in proper writing. And it's all a downhill from there.

I wouldn't be surprised if the internet language of people devolves into a weird constantly-changing mish-mash of slang and linguistic fads. Basically an arms race where people constantly innovate in order to stay distinct from the latest models.

But the end result of that would be probably fragmentation, isolation, and a kind of dark ages. Different communities would have different slang, and that slang would change so fast that old text would quickly become hard to understand.
