You're right about that. At the end of the day it is a tool in the craft domain of art. Artist take a long-ass time to perfect their craft end of the business, but ultimately what sets great artists from mediocre ones is not craft, it's their taste. Own (good or bad) taste pushes artist to not stop working on their image/painting until their own taste is satisfied. Same will happen no matter the tool. I am actually terribly excited by these tools to expedite sketching, not in a sense of speed as much as volume while hunting for those directions that satisfy that inner taste.
