I explained later in my post: limited to the same senses. Also,
though, I should have indeed said something like: consisting
of a single cerebral cortex. I definitely want to exclude some
kind of arbitrary multi-minded computronium-based solution,
because probably no one could argue that *that* would not be

Of course. But as a measure of g, that is, of cognitive ability,
it serves astoundingly well.
* figure out how a fusion energy reactor could be designed,
and write up specifications sufficiently detailed so that
the rest of us could build the thing
* provide a specific outline of how an AGI could be coded-
up following the outline/design by a good software team
in six months
* be able to understand at about normal reading speed any
book ever written, much as you can easily understand and
absorb everything being conveyed by a Dick-and-Jane book

Well, yes. Thanks, this *is* the kind of criticism I solicit.
But it'll take a little more to persuade me; after all I am
positing *extreme* intelligence. No upper bound, (except as
some possible limitation to our architecture).
You are, of course, quite right about knowledge. But the rate
at which knowledge can be acquired is surely commensurate with
intelligence, wouldn't you say?
As for extending IQ, recall how chess and some other straight-
forward tasks work. In chess, you stand the same probability
of defeating a player 100 points below you regardless of your
talent or level of skill (this is how the Elo scale was
devised, and how scales in East Asian sports, for example,
the famous Dan and Kyu, work).
By considering a huge variety of tasks, perhaps it becomes
possible to describe a level of intelligence X such that X
is to 200 as 200 is to 180, and then to call that 220. In
other words, we take enough samples of tasks demanding
cognitive capability, and calibrate our measure accordingly.
(By the way, your examples of wisdom and social skills simply
don't correlate with cognitive ability as measured by
practitioners in the field; they're pretty much in agreement

I wish I knew how you are so confident. Are you saying that
it's flat out impossible no matter how smart a piece of matter
is? Or one limited to, as I say, "human architecture"? I must
hasten to say that by allowing a week (or a month, whatever),
I am supposing that lengthy and costly experiments do not need
to me done, and I could be entirely wrong. Somehow, it seems
strikingly interesting and peculiar if it emerged that no matter
how smart some piece of matter was, all it could do would be to
shrug and say "the data simply is not available, and you would
have to do the following 26 experiments...".

Why isn't it a mathematical function of an information processing
