I feel that human intelligence is not the gold standard of general intelligence; rather, I've begun thinking of it as the *minimum viable general intelligence*.
In evolutionary timescales, virtually no time has elapsed since hominids began trading, utilizing complex symbolic thinking, making art, hunting large animals etc, and here we are, a blip later in high technology. The moment we reached minimum viable general intelligence, we started accelerating to dominate our environment on a global scale, despite increases in intelligence that are actually relatively megre within that time: evolution acts over much longer timescales and can't keep pace with our environment, which we're modifying at an ever-increasing rate.
Moravec's paradox suggests we are in fact highly adapted to the task of interacting with the physical world-as basically all animals are-and we have some half-baked logical thinking systems tacked on to this base.
