It's really hard for me to parse LLM-generated prose in blog posts - the reasoning is disjointed, logic is split everywhere.

Is it already too late to have humans just write down what they are thinking instead of passing it through a lossy expander?

Human writting will come at a premium. I don't think LLM-generated prose goes away at all; the scary part is that I'm starting to catch people adopt the same tropes and language patterns in their speech/writing, manufactured contrarianism for example seems rampant in social media and blog posts ... but I guess nobody is talking about that :D.
