I was thinking that an interesting definition of intelligence might be “your ability to solve problems that a computer can not”. If so, then we might expect that the harder a problem is for AI to solve, the more g loaded the problem is. For example the least g loaded problems on the Wechsler are the processing speed subtests because these require simple rapid decision making, immediate memory & psycho-motor speed. I have no doubt they could program a robot that could score far better on these subtests than any human.
On the other hand it would be very hard to program a robot to score high on the more g loaded verbal comprehension tasks .
