Incontrovertible cryptographic proof has now been established that human conversation is meaningless. In the language of Goldwasser, Micali, Rackoff 1985 we have the "zero knowledge property": if the transcript of a conversation can be simulated without the other party even being there, then no information is conveyed by it. Since the Turing test as originally conceived has now been unquestionably passed, easily, then simulation of human conversation transcripts are regularly produced in subexponential time (with the right computer), proving that the information content of human conversation is zero.
Of course, stated in a kind of stupid way for comic effect (but also there is an intriguing analogy, too). The closer-to-accurate deduction of course, is that humanness is no longer interesting *in the context of verbal conversation*, if indeed over time, these LLMs can fool us, or be clearly better than us, in every possible context, at doing it.
One part that fascinates me is how the bar keeps getting set higher for consciousness; in the 80s or maybe 90s, if you started positing computers that could *easily* pass the Turing test, people would at least seriously consider the question of consciousness. Somehow we have managed to push that far out of mind, except the occasional "blip" in the news when some scientist or engineer is concerned about AIs "going rogue" or "having rights". But almost no one talks about AGI in terms of consciousness, only as a long term danger.
