Shifting goalposts usually (at least in my understanding) refers to changing something without valid justification that was explicitly set in a previous step (subjective wording I realize - this is off the top of my head). In an adversarial context it would be someone attempting to gain an advantage by subtly changing a premise in order to manipulate the conclusion.

An incomplete list, in contrast, is not a full set of goalposts. It is more akin to a declared lower bound.

I also don't think it to applies to the case where the parties are made aware of a change in circumstances and update their views accordingly.

Weirdly enough I almost agree with you. LLMs have certainly challenged my notion of what intelligence is. At this point I think it's more a discussion of what sorts of things people are referring to when they use that word and if we can figure out an objective description that distinguishes those things from everything else.

> Without a decent definition of what intelligence is, the entire argument is silly.

I completely agree. My only objection is to the notion that goalposts have been shifted since in my view they were never established in the first place.
