Nick, thats why I said non-coercively (though looking back on it, that may be a hard thing to define for a super-intelligence that could easily trick humans into becoming schizophrenic geniuses). But isn't that a problem with any self-modifying AI? The directive "make yourself more intelligent" relies on definitions of intelligence, sanity, etc. I don't see why it would be any more likely to screw up human intelligence than its own.

If the survival of the human race is one's goal, I wouldn't think keeping us at our current level of intelligence is even an option.
