Great post. I like to make the comparison and take the idea of artistry beyond music, visual and performing arts, or anything else you'd encounter at your local cultural center.
The better idea is to take Artistry as a concept applicable to all disciplines. You can be an artist in any profession as long as you're humble, and work your ass off to get to the next level.
Once you get comfortable, you slow down. Get busy Livin' or get busy dying.
Look at Google's evolution since 2000, how Apple has taken over music distribution...It's mind blowing how innovation and creativity keep pushing us into the Jetsons era.
Like in jazz, innovation comes from paying respect to the masters, but still developing your own voice.
