This would seem to indicate that you are not talking about strong AI though but merely increasing knowledge and interaction and tool use among humans.


To suggest that we are at the height of human intelligence now strikes me as a very ill conceived notion.
Time to play devil's advocate.

The recursive nature of intelligence may put limits on how expansive it can be. What other species suffers from existential angst for instance?

Humans are the most intelligent species on earth but they do not have the largest brains (though it is the largest in proportion to body size.) Mammals with brains larger than ours should experience greater return on investment for brain mass devoted to self aware intelligence since relative to the size of their brain it costs less. That they are in fact less intelligent indicates diminishing returns for intelligence which in turn indicates a limit of some sort.

Well, the IQ exam was designed to measure a person's raw intelligence and not their accumulated knowledge, but the success of that attempt is disputed. When examining fossils, measuring cranial capacity in relation to an organism's body size can hint at its overall intelligence level, although admittedly the link is tenuous. Humans, being smart, tend to have proportionately larger brains than other animals of the same size. However, the brain size of modern humans is not significantly larger out most distant direct ancestor of 250,000 years ago, suggesting that they were no less smart than us, even if they knew less. Here is a chart comparing hominid skull brain volumes.
