Maybe sometime I'll write a post on why I think the paperclipper is a strawman. The paperclipper can't compete; it can happen only if a singleton goes bad.

The value systems we revile yet can't prove wrong (paperclipping and wireheading) are both evolutionary dead-ends. This suggests that blind evolution still implements our values better than our reason does; and allowing evolution to proceed is still better than computing a plan of action with our present level of understanding.

Besides, Clippy, a paperclip is just a staple that can't commit.
