1) tell me what they were then, 2) It wasn't AI. It was me

It seems too concise to be AI. My (conscious) heuristic for AI writing is how much context is squeezed into a sentence. LLMs seem to be pretty bad at the kind of elegant compression of meaning humans can do when they have done a lot of writing practice.

If I had to guess, I would say this is the human summarised conversation(s) with a bot.
