I think of the Turing test as one of the starting lines, along with image recognition ("a summer break project for a group of grad students" resisted being solved for decades).

It is a huge leap. Now we can start talking about "intelligence" at all - we really couldn't before. That we're still hovering barely above the starting line is a separate matter (also worth noting, of course).

I don’t think he would. The Turing Test as originally formulated is a bit ambiguous but by most non-incentivised interpretations LLMs do not pass it.

In the original test the evaluator knew one was a machine and one a human and could have conversations of arbitrary length.

How are the models too dumb? How are they dumber than the average person? I wonder if anyone gave Claude an IQ test (the one for humans).
