> humans simply didn’t write this way prior to recent years.

Aren’t LLMs evidence that humans did write this way? They’re literally trained to copy humans on vast swaths of human written content. What evidence do you have to back up your claim?

You’re pointlessly derailing a conversation with a claim you can’t support that isn’t relevant even if true.

Regardless of whether AI wrote that line he published it and we can safely assume it is what he thinks.

LLMs learned from human writing. They might amplify the frequency of some particular affectations, but they didn't come up with those affectations themselves. They write like that because some people write like that.

> I didn't mention em dashes anywhere in my comment!

I know. I just mentioned them as another silly but common reason why people unjustly accuse professional writers of being AI.

> I have done a lot of copyreading in my life and humans simply didn't write this way prior to recent years.

What would you have written instead?

Heuristics are nice but must be reviewed when confronted with actual counterexamples.

If this is a published author known to write books before LLMs, why automatically decide "humans don't write like this". He's human and he does write like this!

The author is reputable, just look at the rest of their website.

Your accusation on the other hand is based on far-fetched speculation.
