As I said, Nick Bostrom&#x27;s <i>Superintelligence</i> talks all about this.<p>The main thing is that the constraints of the physical world are nowhere near the limitations of human capabilities. Yes, there&#x27;s a theoretical limit to how much computation you can do in a certain amount of space with a certain amount of energy. No biology or technology currently in existence even gets close to those limits.<p>Without any such fundamental limit there&#x27;s just no reason for AGI <i>not</i> to present a threat.<p>But there is lots of other evidence too.
