There has been many triumphs of science and technology by accidental discovery. Mistakes and accidents made in the lab have sometimes led to incredible discoveries. Mistakes made during DNA combining also leads to new traits which have helped drive evolution. As we create mechanical life, we may have to engineer error potential into the core of the machines so they may use chance and accidental occurrence to advance their existence. Imperfections distributed among the members of a population collectively increases the perfection of the whole. We much inevitably endow machines with this potential.
