The problem with using ChatGPT for translation is that it will highly likely won't be an accurate translation or it might even hallucinate. Additionally the Clockwork Orange is hard to read on purpose, if you use ChatGPT there is not point in reading it; why translate made-up teenage slang. The author wanted the readers to understand it themselves, it is part of the fun.

It is true that people are probably reading more online than in the past, for example many people are probably reading from royal road. I for one used to read from royal road a lot, a lot of books from there even got published like Dungeon Crawler.
But in my opinion, I do think people are reading less due to tiktok, Instagram, and other social media sites. Reading level is going down.
