Christ, there's SO MUCH stuff that hasn't been done yet. AMVing is still pretty much in it's infancy, and whoever's tired of it can stop, but saying you're beyond it is just elitist, anyway you put it. Yeah, there are more complicated hobbies out there, but art never was about complication, was it?
I mean, with the whole CG thing, it feels to me like it's people saying "Hey, I'm tired of skiing. I'm moving on to snowboarding". Yeah, snowboarding is alot harder, and the possibilities trick-wise are far more diverse, but skiing is still fun as hell, and some people happen to find it more elegant and enjoyable to watch. Clumsy metaphor, but you get the idea : There are no superior artforms. With that philosophy, we might've abandoned books by now because we'd discovered the visual medium. And we'd have missed quite a few masterpieces then.
So yeah, that's my point of view, though I'm open to debate
