From Stargate Replicators to Borg-like technology, the question of ‘von Neumann machines’ is both an intriguing and scary concept! Does the fact that they haven’t shown up yet prove that they don’t exist at all (not necessarily!) or are they possibly on their way right now? (Oh my!)

These questions are pretty daunting, but their (theoretical) answers were actually put forth decades ago. Roey Tzezana describes the conceptual von Neumann machine.
