I don't see how. Whatever truth it might hold for a 140/100 IQ gap, it doesn't hold for arbitrarily smart beings, who could tell a lesser being all the self-modifying it would need to do to reach cognitive parity.
In any case, as those who have seen my posts here know, my warning lights go off whenever someone claims that something "can't be explained, even given infinite time and space".
The point being made seems to be the contradiction of a common AI-theorist, futurist position.
That position being that once a computer algorithm of effective AI IQ of 100 is produced, it can increase it's intelligence to arbitrary levels by the addition of additional hard-drive space, ram, and processing power.
IMO the analogy slightly fails. It fails to include anything analogous to the increase in ram, which is a very important factor, as it allows complex concepts to be dealt with as a whole.
