As humans have evolved larger brains, intelligence went up extremely. Human brain size is limited by a lot of factors specific to human biology, like the fact that it needs to be small enough to fit through the birth canal, it can't take up too much of the body's energy, and it can't make us too top-heavy. It seems unlikely that human evolution ran into these limits right at the same time it finished making a maximally-intelligent mind. None of these limiting factors apply to AI. If/when we figure out how to make intelligent software, we make AIs, and then we improve them to be human-level intelligent, it seems really unlikely to me that we'll hit a limiting factor right there. I think if we ever create near-human-level intelligent AIs, we'll blow right past human-level intelligence and hit a limit further on that's not coincidentally placed at human-level intelligence.
