Information is proliferating and is more accessible, but a huge amount of that information is lies and manipulation I'm not sure that really counts as knowledge.
> The idea that I’m going to lose knowledge from a book I read 5 years ago if it disappears from my library just doesn’t track.
You might not forget what you learned from a book you read 5 years ago after it gets stolen from you, but it does mean that others are cut off from that same information. Worse is that what you saw 5 years ago might still be made avilable, but only in censored/altered forms which could easily have you questioning your memory of something you read or saw just 5 years ago.
It's not just an abstract philosophical debate that books and other forms of media are being changed, censored, or removed entirely. Or that gatekeepers want to decide what we're allowed to see and extract rent from us every time that we do. The dangers are real and understood and very much present in today's world.
