I have never seen anything resembling emergent behaviour, as you call it, in my own or anyone else's use. It occasionally appears emergent to people with a poor conception of how intelligence, or computers, or creativity, or a particular domain, works, sure.

But I must push back, there really seem to have been no incidences where something like emergent behaviour has been observed. They're able to generate text fluently, but are dumb and unaware at the same time, from day one. If someone really thinks they've solid evidence of anything other than this, please show us.

This is coming from someone who has watched commentary on quite a sizeable number of stockfish TCEC chess games over the last five years, marvelling in the wonders of thie chess-super-intelligence. I am not against appreciating amazing intelligences, in fact I'm all for it. But here, while the tool is narrowly useful, I think there's zero intelligence, and nothing of that kind has "emerged".
