Earlier quoted context omitted.
You're misrepresenting what I wrote. I specifically pointed out that I switch languages without intent to do so. When you suggest that is a "superficial analogy" after you were the one pointing out LLMs switching language as something that sets them apart, you're seriously reaching. I can often pinpoint afterward what was likely the trigger: E.g. I used a word that is the same in two languages, and continue in the se…
That's a fair point. I agree that the behavior can look similar even when the mechanism is different. But in practice, all the analogies I've seen are in fact superficial, including this one. The LLM that abruptly switches languages will also likely switch to a wildly unrelated topic. If a human behaved that way, you'd call a doctor.
I'm sure there are other failure modes where it may change topics too, just like humans also regularly digress when triggered by certain words etc.
