Why are the writers thinking so small? I mean they have a super collider right? You need the super collider to turn the nanites off and there is a chance that using the super collider will cause the Universe to collapse in on itself and explode in a new big bang. A big bang that the nanites might still survive. And become... The Borg. And also Shatner will be there. And he might also write it.
Ok it may be time to go to sleep.
