In which art is not blamed for the problems of the world:
A man in a controlled, music-less dystopia finds a guitar, learns to play, and feels joy. The priests of Syrinx who rule the system in the name of "average" (a la Harrison Bergeron) crush him. The ancients of rock who created the guitar return and liberate the system with a prog rock concert.
Our world could use this beauty
Just think what we might do
Listen to my music
And hear what it can do
There's something here that's as strong as life
I know that it will reach you
Don't annoy us further!
Oh, we have our work to do
Just think about the average
What use have they for you?
Another toy that helped destroy
The elder race of man
Forget about your silly whim
It doesn't fit the plan!
A game designer dude lives in exile above his arcade, robbed by evil AI & corporate suit. His ex and her dork boyfriend let him into the building, and he goes into the computer world, which the evil AI & corporate suit rule as well. The ancient soul of the machine gives the dork's program access and lets it play Breakout against the AI, and the game designer sacrifices himself, liberating the inner world, deleting the evil AI & firing the corporate suit, restoring the game designer to power in the real world.
A too-young, too-uptight student works for an evil professor, but makes friends with other weirdo students and loosens up. The evil professor and the military trick the weirdos and make a death ray from their work. The ancient student in the closet emerges and the weirdos hack the death ray and turn the evil professor's house into popcorn.
All for freedom and for pleasure
Nothing ever lasts forever
Everybody wants to rule the world
A boy in a crapsack world, literally in a trailer home on top of trailer homes, finds solace in ancient movies and games from a book by an ancient nerd. The corporation which rules the world and the virtual world crushes him and his friends. The ancient nerd's program runs, and gives the boy power and he liberates the virtual world and the real one.
After a long silence she asked, "So what happens now?"
These stories, they're just stories of their time.
2112 didn't end the "Moral Majority" or censors. The PMRC of Syrinx was founded 6 years later to destroy rock 'n roll and rap; the PMRC is gone but Tipper Gore still lives and hates, and music is still censored; remember Fuck You, by CeeLo Green? You probably only heard the censored radio version "Forget You".
TRON didn't end centralized computing, AI, or thieving corporate assholes. Today EA has ruined large gaming, and Google & Amazon make AIs that will probably kill us all.
Real Genius didn't end all CIA/military weapons. Today the babykillers have unmanned drones that can fly anywhere and assassinate anyone (and any bystanders/witnesses).
Ready Player One didn't make the real Internet a "safe space". Facebook, Twitter, or Google can still track you, filter what you see, and give Nazis access to harass you.
This is not a failing of art, it exists for fun or catharsis, and to give you coping strategies. It is not a magic spell to fix everything.
So, you can do something inspired by art; make art yourself; or, if you are completely useless, just whine unreasonably about art and be held in contempt.
