Some of the headings are very AI-cliche: "Hospitality Is a Dialogue, Service Is a Monologue"; "AI Raises the Floor. Humans Raise the Ceiling"; "Your Employees Are the Moat. The Compounding Is Invisible."

The author didn't use headings like that in their 2024 blog posts.

The intro section reeks of LLM slop:

> He called the restaurant. He was put on hold for thirty minutes. When someone finally answered, they were apologetic but firm — the restaurant was fully booked. No warmth. No conversation. Just a long wait and a closed door.

If that was written by a human, it's embarrassing.

I can only speak for myself here, but if I feel like I've read a whole paragraph that should have been half a sentence, that's my signal there's possibly AI generated content in there

One I've started noticing is the "quotation marks around a phrase awkwardly trying to bundle a concept" thing. Like all LLM cliches it's something that has been used in writing for a long time, but I've seen it so much more recently. I think lots of people have picked this up from seeing LLMs use it. But like you said, who knows.

I do have a sneaking suspicion it's a mix of things, I'm at the point now that I do get a bit of an odd feeling whenever I'm reading AI produced content

I suspect over time it will get good enough that I'll need a larger sample size to identify it, however that won't solve what I think of as the "why does this need to exist" problem, I've noticed that a fair bit of AI content hits that mark, it can be fun, but I've not experienced that feeling of engaging with something that's been well thought out / executed, maybe we'll hit that point[0], but I suspect it will take a while
