Logic terminator

h+ magazine: "Is a Terminator scenario possible?" (Found via Instapundit.) Interesting, but I'm left nonplussed by this statement from J. Storrs Hall of the Foresight Institute:

...if all you mean is are the robots going to take over, it's more or less inevitable, and not a moment too soon. Humans are really too stupid, venal, gullible, mendacious, and self-deceiving to be put in charge of important things like the Earth (much less the rest of the Solar System). I strongly support putting AIs in charge because I'm dead certain we can build ones that are not only smarter than human but more moral as well.

Leaving aside the one-dimensional view of humanity and the nastiness of wanting our species to be enslaved, isn't there a problem of logic here? If humans are so venal, gullible, mendacious, and self-deceiving, how can we trust ourselves not to build robots that are just as bad (or worse)?
