Enjoyed reading this greatly! I'd say all kinds of work require creativity or, shall we say - artistry. Whether it be engineering design, theoretical physics or even accounting! You're of course spot on that what distinguishes art is it purely focuses on offering intellectual and emotional utility. Most other professions aim for a combination of intellectual and material utility.

I like to think science is a way for us to know the universe*, art is a way for us to know about ourselves.

*Or we (or any intelligent species) are a way for the universe to know itself :)
