There are a host of different definitions, which are not closely entangled with simple, observable features of the world.
I believe that at least two of those definitions could be something like, “what kinds of humans would consider this art ?”, or “will machines ever pass the Turing test”. These questions are about human actions which express human thoughts, and are indeed observable features of the world. I do agree that there are many other, more personal definitions that are of little use.
