I have a feeling that these ad-hoc bars for AI to clear are extremely similar to Plato's definition of a human ("a featherless biped"), in that they look for what features a human/intelligence has, but don't incorporate the flip-side. Hence the large amount of Diogenian refutations; including plucked chickens, chess computers, visual classifiers, generative AIs, LLMs, and now, I guess, proof generators (which already exist in some form or another) that could loudly proclaim "behold, a human!". Unless we rigidly define what intelligence actually is, how can we even hope to correctly identify one?
