Agreed. A lot of what we call intelligence is really speed - both in the short run (how long it takes you to add two numbers in your head, for instance) and in the longer run (how long it takes you to accomplish your ambitious projects). Ten million dollars would free up so much time and let you fake so much long-term speed that it would almost certainly be a gain if you got it for one IQ point. Not that anyone's actually offering this trade.
