> you will be chatting with someone who putatively has a real name and a physics pedigree, and you ask them to answer physics questions, and they appear to have a really vast physics knowledge, but then when you ask them a simple question like "and because the force is larger the accelerations will tend to be larger, right?" they take an unusually long time to say "yep, F = m a, and all that." And that's how you know this person is pasting your questions to a GPT prompt and pasting the answers back at you.

Honestly, (even) in my area of expertise, if the "abstraction/skill level" or the kind of wording (in your example: much less scientifically precise wording, "more like a 10 year old child asks"), it often takes me quite some time to adjust (it completely takes me out of my flow).

So, your criterion would yield an insane amount of false positives on me.
