"When building technologies to deal with uncertainty, we use constraint(s)." #readingToday
The way 'control' emerges in a quantum mechanical sense is in the manipulation of guard-rails or constraining walls, forces called potentials: containers that limit the probable range of electrons to an approximately predictable region. This is not control, but loading the dice by throwing other dice at them. Similarly, when building technologies to deal with uncertainty, we must use similar ideas of constraint.
