Besides the obvious censorship, and rewriting the past being a bad thing. I can't wait to see what they do to "Brave New World", "Fahrenheit 451" and "1984". It'll be ironic and sad if they burn the old unedited Roald Dahl books.
But also have we reached cultural stagnation, that old media still out competes new ones by such orders of magnitude ?
This is a huge problem, when every year we graduate more and more people wanting to be writers, artists, etc. This will only get worse with books now being written by ChatGPT and art by Dall-E/Midjourney/Stable Diffusion.
Have we reached "peak multimedia" content ?
You can see it with successive movie adaptations: the decorations are the same, but all the messages get reversed, they focus on action, and they add hopeful endings.
