Re "ChatGPT translation is bad": The article made a very particular claim, so we can check it in context. Is it bad at translating Clockwork Orange into modern english? I'm betting no, it's an old book with tons of helper material online to train from and use. But I welcome evidence to the contrary.
Re "Hard to read on purpose": This is the same argument against difficulty modes in games, and accessibility features in general. I find this entirely uncompelling.
Re "People are reading less": There's data here, and it largely supports your opinion.
