That sounds plausible. On the other hand, it might be another case our tendency to judge intelligence by the already existing intelligence that we know of, which is us. But we probably shouldn't assume that that is the only form of "intelligence" that exists.
Related to that: these types of discussion tend to get rather fuzzy because most of the words involved ("intelligence" especially) aren't nearly as neatly defined as our gut feeling tends to make us believe. And depending on which interpretation people pick they can wildly talk past each other, or even confuse themselves by not realizing they're switching between which aspect of intelligence they're talking about in the middle of their argument without realizing it.
Which is precisely why I don't really feel the urge to go deeper into what might be needed for AGI right now though, apologies. I think we maybe should put a bit more effort into understanding humans first.
