Why do you think I'm angry? Where is your evidence to back that up? All you're giving me is a vague depiction.
Really though, it's just as silly to assume that the artists won't be iconic in the future than to say that they will be. The Beatles were written off by many as a passing fad but they ended up being icons. Unless you wanna give me a ride in your time machine I think judging from today's events is the only way to determine icons. Kanye comes to mind.
