That would require philosophical work, something that the technicians building this stuff refuse to acknowledge as having value.

Ultimately this comes down to the philosophy of language and of the history of specific concepts like intelligence or consciousness - neither of which exist in the world as a specific quality, but are more just linguistic shorthands for a bundle of various abilities and qualities.

Hence the entire idea of generalized intelligence is a bit nonsensical, other than as another bundle of various abilities and qualities. What those are specifically doesn’t seem to be ever clarified before the term AGI is used.
