Art they are. Of course just like art you have stuff that will be held in high re-guard for decades to centuries.. if not for the length of all humanity. But on the other hand you also have that picture at Walmart that you see in every restaurant and doesn't mean a fucking thing to anyone other than being more than an empty wall.
Only time will tell of course. But sure some of them will go down as true master pieces of art. Mostly though they will be floating on top of a sea of garbage. Either way art is art.
