It's not "moving the goalposts." It's realizing that the principles behind perceptrons / Lisp expert systems / AlphaGo / LLMs / etc might be very useful and interesting from a software perspective, but they have nothing to do with "intelligence," and they aren't a viable path for making machines which can actually think in the same way a chimpanzee can think. At best they do a shallow imitation of certain types of formal human thinking. So the search continues.
No, it's still moving the goalposts. It just that we move the goalposts for pretty good reasons. (I agree!)
Btw, you bring up the perspective of realising that our tools weren't adequate. But it's broader: completely ignoring the tools, we also realise that eg being able to play eg chess really, really well didn't actually capture what we wanted to mean by 'intelligence'. Similar for other outcomes.
