Is Art Theory Moving On?

I have seen little evidence from recent graduate shows that art theory has moved on. To me, it is the act of creation that is most important. Once the piece is complete, it is handed over to others to make off what they will. The artist Maggie Hamling once said, great art inhabits a mysterious place between life and death - simultaneously composed of both. So, becoming an artist, approaching the age of 60, and since then attempting to create the best I am capable of, is perhaps a good way to prepare for death.
