I was thinking about this topic during Thanksgiving, when the old electric turkey slicer came out of the closet, hehe. Ang seemed to be saying that when you electrify a natural process, watch out for fireworks! That's what happened when the electric knife replaced Jack's paring knife that he used to peel potatoes while Ennis was stripping. Fireworks also happened when Jack's beat-with-a-stick in the stream method of laundering (and Alma's washboarding) was replaced with the electric washers and dryers in the laundromat.
