I believe art should have a lifespan. Pick your favorite painting, then imagine that painting will be destroyed in 1 year. By destroyed I mean completely. No remains, no ash, nothing. It is gone. Like it never existed. Would you make an effort to go and view it one last time? Or would you just rely on existing photographs?
Would people mourn it’s passing? Would it have an obituary written about it? Would it become more popular, important, powerful after it is gone? Or would it be simply forgotten?
