Contemporary Art Conservation: An Ongoing Battle

Came across this article on contemporary art conservation and it made me think about the future of art conservation.  How will it have to change to adapt to ever changing materials and the potential of materials which no longer exist?  The conservator in this article says: “…you can choose a medium now, and in two years it might not exist.”  Wow. http://www.koreatimes.co.kr/www/news/art/2010/07/148_69118.html
