Even if human intelligence was the pinnacle, AI could be still extremely dangerous just by running at accelerated simulation speed and using huge amounts of subjective time to invent faster hardware. See <a href="https:&#x2F;&#x2F;intelligence.org&#x2F;files&#x2F;IEM.pdf" rel="nofollow">https:&#x2F;&#x2F;intelligence.org&#x2F;files&#x2F;IEM.pdf</a> for discussion. The point is moot anyway though, since the hypothesis (that humans are the most intelligent possible) is just severely incompatible with our current understanding of science.
