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 ?
Where is the next Dahl? Why is there no modern Beatrix Potter? Kids still love those stories and style of writing, which is less trite than most of the modern children's books.
It does feel like stagnation, with lots of content being churned out but none of it with great staying power. Instead the old stuff is regurgitated endlessly with less and less of it's original soul.
I visit the bookstore with my kid regularly. She's 5. My older kids 11 and 14 do find plenty to read, but I disagree that there are plenty of magical modern children's authors capturing the 3 to 10 year old space. There are a lot of books, mostly dross.
And the stories... "I loved my cat/mom/dad then they died" I get it sad stuff happens and kids need to process it but these aren't books that are going to delight. "Your cat died so I got you a book about someone's cat dying"
Dahl's best-known book is about a family of 7 that can barely afford to eat. One of his other famous books is about how giants stalk through the night to kidnap sleeping children and eat them. A third one is about a child prodigy who is treated to the point of mental abuse at home, finally gets to go to school, only to encounter physical abuse - by the folks that are supposed to keep her safe!
If you think those stories can do more than terrify and scar children for life, I see no reason why you'd be dismissive of other works in which far, far less horrible stuff happens.
