> Humans, the only examples of general intelligence we know
Our intelligence only seems "general" to us, because we're viewing it through our own eyes. Our "intelligence" is specialized to our survival, and we're terrible at most tasks outside that scope.
We operate and think about subjects like Higher Topos Theory, Information Geometry and Algebraic Topology, which are several layers of abstractions removed from anything that can be termed as a skill “specialised to our survival”.
