Thirty years? Anime might be extinct by then...or to censored to watch, who knows. I can't say for sure, but if I can still access anime as easily as today, sure, why not. Anime are like books, you never get tired of them as long as something new is around
I stopped watching TV the day I started watching anime, so if something new comes up, the possibility of dropping anime to do something else is rather high as well.
