questions for first reading

1. it seems like when postmodern art strives to break outside the studio, and "embrace a wider framework for art production," it's another step along a constantly widening "framework" throughout time. Our influences are constantly multiplying, and our production methods are becoming more diverse as time goes on. Won't this inevitably lead to the word "art" becoming meaningless, as what is called art is so diverse that each piece can't be intuitively categorized with another?
2. to what degree does the artist own their artwork, now that there are so many layers of technology and influence that guides them? Perhaps they even took an image as a starting point and created a variation of it, does the artist own that piece?
