Nanotechnology couldn't come to fruition since nano-fabrication at this point in time just doesn't exist in an effective form. Having to manually assemble a complex nanomachine one molecule at a time isn't viable. Until there's a way found to make the machines assemble themselves from the simplest possible unit then we're going to be stuck with just nanomaterials which is great IMO. Nanodust has many uses and we're discovering many dangers (health hazards) now.
