The quest for some constrained and denotative definition of โartificial general intelligenceโ is daft and pointless.
When does a 747 become a bird? When is a submarine a fish? When you ask an amorphous, unfocused question all your answers are disjunct from the set of possible paths to revealing the actual important questions, much less any answers.
Iโll leave it as an exercise to the reader what the important questions are. But suffice it to say that though I believe some form of human-level machine intelligence is possible, weโll never succeed in making a submarine into a fish, and weโll also never accomplish the feat of transforming silicon and transistors into a human. A person, perhaps. But not a human.
