It’s not all roses though—to quote Garrison Keillor, “being intelligent means you will find yourself stranded in more remote locations”
To elaborate a bit, I think there are layers in-between raw IQ and practical proprioception, for instance. Balancing one's body involves the full neural chain, down to origin (which is the end-cell, the sensor/motor device), and quite evidently can be trained to orders of magnitude more accuracy.
So to think like a tech stack of sorts, from the meat (purely biological, since the first unicellular organisms) to the highest-level (call it 'sapience', 'wisdom', whatever; that which is even above IQ), you'd find something that goes
good-enough bodily genetics + trained sensor & motor neural precision + high IQ for good aim and strategy + sapient decision-making
in order to best navigate complex spaces.
Case in point: cliche nerds (not your best dancers/athletes), unwise yet very intelligent people, bad draw at the genetic lottery for negative examples; conversely a very gifted "natural born" athlete or musician (which doesn't mean that without training they wouldn't get beaten flat by any seasoned professional) doubling as a strategy prodigy, or zen master, whatever 'wise-r.'
If we admit that space[time] is the "language of the brain" (what IQ actually tests), and therefore that even social spaces—like love, business, or politics—are navigated from the same core skills than physical spaces like sports. (That much perhaps is a stretch, it may be more complicated; but perhaps partially true for 'core functions' as it were. Perhaps like 'speech mastery' alone is a core function that contributes to a slew of more complex tasks/goals).
In fact, I'm somewhat of the position that nearly any grounding in a domain of shared objects where signalling is inexpensive would be suitable. That said, AI agents which grew up in some alien domain of shared objects would find us as unintuitive to reason about as we find quantum mechanics uninituitive to reason about. If the goal is AI that acts and talks like us, your way may be the way to go.
Your last sentence strikes me as particularly validating.
"My way", this framework, was meant to give a mechanistic description of our individual, subjective "inner world." Much like physics speaks of the outer, shared world; and in compliance with all objective 'hard' sciences.
Indeed, it lends itself particularly well to be exploited by AI, notably in terms of architecture and domain-selection (by whatever core we call 'sapience') within a "Mixture-of-Experts" paradigm of sorts—which biology seems to have done: dedicated organs or sub-parts for each purpose, the Unix way to "Do one thing and/to do it well."
