The lab bustled with activity.  Computer arbiters seized their processing machines, wrenching the controls furiously.  Involuntary facial expressions on the faces of these young 3d world builders allude to a subconscious turmoil, a pull between potentiality and reality.  In their minds millions of tiny skirmishes are taking place on a microscopic level.  At a crux, when a neuron faces the impasse of two choices, one synaptic branch or the other, this is the firefight.  A metronome of futures engaged in combat.  There can be only one.
