It's LLMs. You can tell from the phrasing ("no X just Y", "isn't A it's B", "pure ___"), and because all of the sections except Screenshots say basically the same thing. A competent person would not write it like this and an incompetent person would not be this meticulous about grammar and formatting.

I realize this sounds exactly like "I can tell from some of the pixels and from seeing quite a few shops in my time" but I really can tell.

Edit: Also you can see this was made with https://github.com/features/spark, but that's cheating, it's more fun to make accusations based on vague feelings about the writing tone.

I wonder where LLMs got this style from, since, while you did see something like it, it wasn’t nearly as widespread before the rise of ChatGPT, so not the most statistically likely form for these to be generated in.

Was it trained into them in the supervised or reinforcement phases?

Has it emerged from prompts extorting them to be friendly, somehow sneaking in from text message training as a result?

Is it now in a self-reinforcing feedback loop as training data grows to include modern Readmes?

As far as I know, it was trained in because people preferred it in A/B testing

Private chats maybe?
