What gives you the sense that the piece was written by an LLM? I would agree that the diagrams have some of the artifacts common in Nano Banana output, but what tips you off about the text?

Em dashes in every other sentence. I've never seen an actual person do that. The language in general reads exactly it's written by an LLM:

"The blah blah didn't just start as blah. It started as blah..." "First came blah -- blah blah blah" "And now: blah"

It's a distinctly AI writing style. I do wonder if we'll get to a point where people start writing this way just because it's what they're used to reading. Or maybe LLMs will get better at not writing like this before that happens.

I'm sick and tired of the "No..., no ..., (just) ..." LLM construction. It's everywhere now, you can't open a social media platform and get bombarded by it. This article is full of it.

I get it, I should focus just on the content and whether or not an LLM was used to write it, but the reaction to it is visceral now.
