The Provenance of Human Triumph

If we make something more intelligent still, it will inexorably triumph over humanity. This hypothesis about the provenance of human triumph seems wrong. Interlect surely helps, but humans look to be powerful largely because they share their meager intellectual discoveries with one another and save them up over time. You can see this starkly by comparing the material situation of Alice, a genius living in the Stone Age, and Bob, an average person living in 21st century America. If you make AI which is merely as smart as a human, you shouldn't then expect it to do much better than agenius living in the stone age. That's what human-level intelligence gets you, nearly nothing.
