Hello, GnomeWorks! (heh, I'm only 43)
I want a game that can give me things like what I've seen in the Redwall series, in Last Airbender, in anime like Cowboy Bebop and Samurai Champloo. We've got to be able to follow the style of things like Harry Potter, because that is today's fiction, today's stories, the things my generation is familiar with.
Let me start by saying I agree with your basic point (once you strip out the hyperbole and provocation

): D&D would benefit from more recent influences.
I'm intrigued by your use of
Cowboy Bebop as an example. Personally, I love it, consider it a masterpiece. I'd be fine with it informing the next D&D.
However, it's a work that never would have been made if it's creators took your advice about ignoring the "irrelevant" stories/art from the past.
Because Bebop is
made out of them. Lots of them. And in it they're made new and "relevant" --note: I dislike that word in the this context, but whatevs.
How relevant were Westerns to you, prior to Cowboy Bebop? Or film noir? Or neo-noir? Or French New Wave cinema? Hong Kong Triad movies from the 1970s? Or any of the other references/tropes/stock characters/plots that Cowboy Bebop is fashioned out of?
Take Spike Spiegel. He's based on a previous anime character from the 1960s, Lupin the 3rd (if Lupin was also part Bruce Lee, and was drawn by John Woo and Jean-Luc Godard working together). Bebop may well be a "genre unto itself", but it relies on and refashions decades worth of previous works.
Speaking of Lupin... it's the 40th anniversary of the character. We've seen multiple series, multiple feature films, including Hayao Miyazaki's debut . One of the most acclaimed anime this season is,
Lupin the 3rd: The Woman Called Fujiko Mine. Still going strong.
And that's 40+ years of Lupin as
anime. The character traces his roots back to Maurice LeBlanc's crime/detective stories first published in 1907 (Lupin III is the original's half-Japanese grandson). I wonder how relevant LeBlanc's stories were in 1960s Japan, at the time Monkey Punch found inspiration in them?
Have I belabored this point enough?
