Source sentences:
text: Theoretically, several suggestions for control have been put forward: limits on replicative capacity; wide dispersion; operational energy and chemical element requirements; the use of rare materials (such as diamonds or titanium) to create molecular assemblers so that they do not turn on humans, who carry infinitely small amounts of these elements; using built-in controls to prevent the grey goo scenario; early detection of destructive self-replication by vigilant monitoring; and rapid deployment of an effective defense.
