By any quantifiable measure, yes, and not by small numbers either.

Until someone can demonstrate a quantitative measure of intelligence - with the same stability of measurement as "meters" or "joules" - any discussion of "Super-AI" as "the most dangerous X" is at best qualitative/speculative risk narratology, at worst discursive distractions. The architecture of the "social web" amplifies discursion to a harmful degree in an open population of agents, something I think we could probably prove mathematically. I am more suspicious of this social principle than I am scared of Weakly Godlike Intelligence at this moment in history; I am more scared of nuclear weapons than literally anything else.

People think we are out of the woods with nuclear weapons, but I don't think we've even seen the forest yet. We are Homo Erectus, puffing on a flame left by a lightning strike, carrying this magic fire back to our cave.
