Speleology aside, just a few days ago in one of HN discussions I was told LLM-produced content is already indistinguishable from human-made. But I'm sure I would have pretty good chances to correctly guess even the exact brand which helped to write this sloppy text. And it's the same with many stories I read.

Stake the claim then. I’ve also read a fair bit of LLM text and this didn’t trip anything for me.

Edit: after reading the author bio and the other articles, I agree with this assessment. Though I will admit, this particular article didn’t jump out as AI to me.
