A year of training would have anyone reproducing picassos art with likely high accuracy. A year of training in calculus is effectively what you have with juniors in high school. To be honest, saying it would take most people a year to reproduce picassos artwork feels very generous. His artwork is not particularly skillful.

his point is that the skill does not lie in the manual process of making the art, but in the process of _creating_ the art. copying something (even with a high degree of precision) is less difficult than imagining the thing in the first place.
