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.

Moving the goal posts and noticing that that you mistook the street lights for goal posts is not really the same.
