Is there a clear contradiction between 'Software can prevent lines from being cut twice; it can control the touchy job of cutting the apex of wedge-shaped pieces by approaching the point from both sides of the wedge rather than attempting to cut around the tip.' and 'Cutting lines is such a touchy job because they have electrical currents.'
