Language evolves and humans had strong locality what gave us many languages. I saw that for very long as a curse – people that don't understand each other are more likely to fight each other. And I'm still convinced there would be less war if we all spoke a common tongue. LLMs are limited to a tiny fraction of languages still, so they will drive out of existence smaller languages but they will also help if not preserve then at least conserve those. Writing and talking is thinking! But reading what you wrote to polish it is also thinking. If you got derailed by my m-dash above, let me assure you this text was not authored by an LLM (unless of course we have LLMs in our heads). It was merely assisted by a spell checker ;) For public posts I always polished a bit and read my posts at least once before hitting send. Maybe that's off-putting to more and more people in the age of LLMs? I hope not because if your post wasn't worth to be read by yourself, why should I read it? If a post is riddled by typos, I don't read it. tldr: If the machine can help you express your ideas better, what's wrong about that?
