We are smarter, whatever that means. But not by that much. Our main differantor is technology. If you went back in time and looked at a feckless human tribe hunting it would not be that different than orcas, wolves or any other social mammal predator.
With hands to build tools that build machines and books to communicate. Basically dialing advantages of hunting in packs up in orders of magnitude over time.
Similarly, "the computer is a bicycle for the mind."
