alt Hacker NewsI don't see how that would follow. If we are talking about "intelligence" in the formal sense of induction/prediction then it is a profoundly memory-hard problem as a matter of theory. This is to "learning" what the speed of light is to physics.
You can't replace the larger simulation required (i.e. more state/RAM) with a faster processor.
Sticking with the computation analogy, it could be a long-term memory look up. If memories were passed down the generations, people could simply memorize actions of individuals deemed smarter. Over a large sample size, a heuristic would emerge. Kind of like knowing there is always a sunset following a sunrise without understanding the solar system.
