We know that this amount of intelligence was a huge evolutionary advantage. That tells us nothing whether being twice as smart would continue to give better results. But arguably the advantages of intelligence are diminishing, otherwise we would have much smarter people in more powerful positions.

Also, a big tongue in cheek but someone like John von Neumann definitely had superhuman intelligence.

Smart people get what they want more often than less smart people. This can include positions of power, but not always — leadership decisions come with the cost of being responsible for things going wrong, so people who have a sense of responsibility (or empathy for those who suffer from their inevitable mistakes) can feel it's not for them.

This is despite the fact that successful power-seeking enables one to get more stuff done. (My impression of Musk is he's one who seeks arbitrary large power to get as much as possible done; I'm very confused about if he feels empathy towards those under him or not, as I see a very different personality between everything Twitter and everything SpaceX).

And even really dumb leaders (of today, not inbred monarchies) are generally above average intelligence.

That doesn’t contradict what I said. There is definitely a huge benefit to an IQ 110 over 70. But there is not that big a jump between 110 and 150, let alone even further.

Really? You don't see a contradiction in me saying: "get what they want" != "get leadership position"?

A smart AI that also doesn't want power is, if I understand his fears right, something Yudkowsky would be 80% fine with; power-seeking is one of the reasons to expect a sufficiently smart AI that's been given a badly phrased goal to take over.

I don't think anyone has yet got a way to even score AI on power-seeking, let alone measure them, let alone engineer it, but hopefully something like that will come out of the super-alignment research position OpenAI also just announced.

I would be surprised if the average IQ of major leaders is less than 120, and anything over 130 is in the "we didn't get a big enough sample side to validate the test" region. I'm somewhere in the latter region, and power over others doesn't motivate me at all, if anything it seems like manipulation and that repulses me.

I didn't think of this previously, but I should've also mentioned there are biological fitness constraints that stop our heads getting bigger even if the IQ itself would be otherwise helpful, and our brains are unusually high power draws… but that's by biological standards, it's only 20 watts, which even personal computers can easily surpass.

On a serious note though a person with an IQ of 150 can't clone themselves 10k times.

They also tend to have some level of autonomy in not following the orders of idiots and psychopaths.
