(3) is doing almost all of the moral lifting, in that it assumes that relatively few of the books get pulped in the first place:
> 3) Many of these pallets may sit for years before being sorted, and many of the books may sit for years before being sold, but these things actually do eventually happen, valuable books are found, and they eventually make their way to interested readers, this is the business model of used bookstores. Most books of value don't get destroyed or thrown away.
This contradicts base reality, as the vast majority of the books in such cases were already queued to be pulped.
> Destroying human art, knowledge, and culture is an essential part of the business plan for frontier labs, it is not enough to steal and regurgitate all the art and information in the world, you also want to make it inaccessible through any other means than the regurgitation machine.
Even if Anthropic wanted to make the books publicly available as a form of moralwashing, they legally can't do that. Their current process rides the line of fair use, in that it obeys the requirement of medium shifting to be considered legally defensible.
Don't like the outcome? Change the law to allow for digital archival without requiring destruction.
