Prove me wrong.
So books in the 2060s will be either totally indecipherable or commercial rot?
Western culture had a good run, I guess.
So... books in 50 years will be:
Futurist literature was already there in the 1920s.
Excessive Haste, a play by Verlaine.
Leck mich am Arsch
painting is gay
Literature is the only medium besides music that has been in a healthy state for a long time now.
Animation, film and games all gave in to the temptation of commercialization only a few decades in to their existence, becoming trend-driven and losing the ability to have the staying power that works in older mediums can. Once a work in any of these mediums passes the 40 year mark they hit their expiration date and slowly fade out of culture.
