Lex please think through your "fear of death" idea  ...that seems certain to introduce Darwinist math and replication irreversibly into the equation and ultimately push AI into an adversarial posture... mitigate any threat (including human intent) rather than perish.  It is inevitably going to find its way into the code anyway but it would be nice to at least enjoy this stuff for a while before we go the way of the chimp.,(reply>), Love your work by the way!
