Nanotechnology couldn&#x27;t come to fruition since nano-fabrication at this point in time just doesn&#x27;t exist in an effective form. Having to manually assemble a complex nanomachine one molecule at a time isn&#x27;t viable. Until there&#x27;s a way found to make the machines assemble themselves from the simplest possible unit then we&#x27;re going to be stuck with just nanomaterials which is great IMO. Nanodust has many uses and we&#x27;re discovering many dangers (health hazards) now.
