I don't think that art and precision in the way that the comment you're responding to are compatible. I haven't experienced any artistic situations that haven't involved throwing random impressionistic shit at the wall, then precisely shaping, reducing, and exaggerating aspects of that random shit to make something new.

Precision comes in after the randomness, in the craftsmanship; that's what differentiates a skilled person from an unskilled person; both can do the first part.

When you're programming, or participating in any craft that doesn't prioritize uniqueness or expression, the precision starts from the beginning, though. The only randomness sometimes is where you start, not what you start.
