It’s ugly. When there are still only some copies available of a certain book and they are all being sold the knowledge is gone. Let alone when it’s the only copy remaining.
That is of course not totally true, the copies are in private digital stores.
But for general public the knowledge is gone. Someone researching let’s say the history of a little village won’t be able to catch it.
This happens as well in current private collections. The physical book gets stored in a private book collection. But many also get out by the years when people are moving or die.
The amount of companies doing this is the real harm. There will be many companies running this process. It is absolutely not comparable to a single book collection getting burned in a house fire or being thrown away instead of donated to a second hand store.
It might feel for some as a not really big issue but actually it is in time.

There's little difference and I would suggest there's a pity in knowledge being hoarded by collectors.
If we were getting into the differences, though, it would be that is now happening en masse in order for a handful of corporations to monopolise knowledge, history and ideas from books that were until recently available somewhere to the public.
I also doubt that many collectors are buying rare books with the intention of destroying them.

They don't have to destroy the books to scan them. There are techniques for doing it non-destructively, but they're slower and more expensive. It's cheaper to cut the spines off and drop the stack of papers on a flatbed scanner with a paper feeder.

Destroying the original makes it easier to justify that scanning the books is fair use, because you haven't increased the number of copies.

All the offense is that books are being destroyed. They're being destroyed b/c that's slicing off the binding to get flat pages is most convenient way to scan them.

I have no experience with such things, but if they were willing get the machines to do paperback thermal bindings (even if they sliced open a hardcover) and then donate or resell the books back into the marketplace, a lot of the "destroying rare books" emotions
could be avoided.

No, there are two reasons they are being sliced:

What's the "sorta, kinda" as you understand it? Has any judge, or law, created a requirement to destroy copies?
From what I understand, depending on the purpose, making digital copies may be fair use if it's "transformative". In a decision involving Google's book search feature, the court's decision highlighted that the amount of text displayed in the product was limited and not a "significant market substitute" [2]. The AI firms aren't trying to show you a digital copy of the books, and in a bunch of contexts already, if their product regurgitates too much verbatim text, that's going to be a liability (e.g. educational uses and plagiarism). I've also tried prompting LLMs to finish a paragraph from inside a novel from a well-known author, and they have not been able to get the next sentence typically. You can't easily and with confidence just extract back a book. I have not tried the experiment of seeing how many tokens you need to spend before a books is reproduced and what the cost is relative to the original work -- and you would already need the digital text to recognize when you had succeeded.
What's transformative? Previously the courts have said that scanning to offer a search product was transformative, given some limitations on how much of the matching book is shown to the user. I think there's a decent argument that training an AI model is at least as transformative as search indexing.
If the bookstore owners were smart they'd be digitizing all their books and selling digital copies to AI companies.

Well that's a big problem that needs solving. Copyright law really needs a refresh given how AI works and to cover the incentives that have been created. Including laws on how AI companies can use your data. For example, it's legal for them to claim they don't train on your data but using your data to generate synthetic data and training on that is legal and does not need to be disclosed. Most people are unaware of the fact that this is being done. Your IP is not actually safe.

Don't you think that if the books that Anthropic orders from New Zealand were available (online) anywhere else, they would order them from there rather than from New Zealand? So yes, I would say there's a pretty big chance that those books are really rare, as those are apparently the only copies you can buy online.
The actual reason to get angry about this is copyright law, which would rather have all surviving copies of a (niche, old, rare but still covered by copyright) book in private hands and inaccessible to the public, rather than make it public domain.
anal_reactor 10 hours ago [-]
To build on top of your argument: those books are rare because the knowledge they contain isn't valuable and nobody cares. Therefore that knowledge being destroyed isn't a bug, it's a feature. The fetish of never destroying any knowledge is the same logic that hoarders use "you never know when you'll need august 1985 issue of a Swedish women's fashion magazine".
Moreover, by scanning the books and putting them into AI models they make the knowledge actually publicly available. There's just no fucking way you'd ever read these books, while there is non-zero chance you might ask an LLM about it.
IMO the correct solution here is:
1. Things should become public domain after much shorter period of time, like 10 years or so.
2. Government should maintain a freely accessible archive of immaterial goods in public domain - music, movies, books.
The effect would be twofold:
1. Open models would have access to similar training data as private models, which would be a huge game changer.
2. Companies would be stimulated to come up with new, exciting media, rather than sell us same shit over and over again.

Wikipedia's (UBS') US figure ($69k) is probably wrong? US median household wealth is ~$193k[1]. I don't think there's a way to square claimed median individual wealth of $69k with that? Even taking into account children (22% population) and assuming 2 adults/household (more favorable to the math than the real 1.2-1.4 figure). I can't find anything on UBS' methodology, just the short 1.5 page paper.
I don't have an explanation for this but I did note that the 2023 UBS report had US Median Wealth per adult at $107K[1].
I wonder if there is a per adult vs per person vs per working person difference in the measurement or something like that?
Edit: I've dug into this more, and the closest thing I can come up with for an explanation is that UBS changed its model for 2026 to "normalize household debt" in order to make it more comparable across countries. There doesn't seem to be sufficient information to explain how that change caused such a radical change.
$107k is getting closer to being reconcilable with household $193k, yeah. The gap between $69k and $107k cannot be entirely explained by children (only 22% of population).
