It would be more accurate to say that an FAI needs to look at humans to
find the specification of how to compute morality. It's like a sentient
calculator that wonders "What is the Multiplication?" where the
Multiplication turns out to consist of multiplying 6 x 7. The Calculator
is pretty sure that the answer is somewhere in the vicinity of 41 or 43,
although different Calculators have been known to disagree on the subject.
But certainly a superintelligence would know that the Multiplication was
41, or 43, or whatever; not return preposterous answers such as 4 or 30,000.
Unless the superintelligence happened to contain a question, "What is the
Multiplication?", that consisted of multiplying 2 x 2 or 300 x 100.
If you presented this scenario to Calculators who did not quite understand
how Multiplication worked, they would laugh at the idea that a
superintelligence could get the answer so blatantly wrong - thinking that 4
or 30,000 was the Multiplication! The Calculators may not really
understand how Multiplication works, or whether the answer is 41 or 43, but
they know a superintelligence wouldn't be that stupid. Even if a
superintelligence started out with a Multiplication of 4 or 30,000, surely
it would look over this Multiplication, realize how silly and inappropriate
it was, and choose a better Multiplication like, oh, say, 45 or 39; it
might seem a little alien, but not something grossly wrong like 4 or
30,000. Would not the superintelligence realize the meaninglessness of 4,
that it cannot possibly result from multiplying 6, let alone 7? Maybe the
superintelligence would multiply 6 by 2/3, but that seems implausible.
Note that all Calculators, if they knew more, thought faster, were more the
people they wished they were, had grown up farther together, would
uniformly agree that the Multiplication was exactly 42; and in this sense
their Multiplication is as objective as mathematics. The Calculators'
mistake is to think that the superintelligence's Multiplication must
necessarily ask the same implicit question.
I now quote Damien Broderick and Adrian Tymes from a recent discussion on
the Extropians list:

Funny how natural selection hasn't picked a different optimization
criterion than reproductive fitness.
