Well to begin with I don't really think Rand was concerned about human extinction, though I haven't read much so maybe you can enlighten me. She also used the word reason a lot. But it doesn't really follow that she was actually employing the concept that we call reason. If she wasn't then thats where she went wrong. He writing is seriously chalk full of obfuscation, conflation and any close to every logical fallacy. Even the quotes you gave above are either inane trivialities or unsupported assertions. There is never an attempt to empirically justify her claims about human nature. If you tried to program an AI using Objectivism it would be a disaster. I don't think you could ever get the thing running because all the terms are so poorly defined.

So it just seems like a waste of time to listen to Eliezer talk about this.

Edit: I think I only voted down the initial suggestion though. Not the ensuing discussion.
