Amazon is buying massive quantities of books, scanning them for AI training data, and destroying them in the process. 

A 404 Media investigation was able to reveal Amazon’s book buying operation, which hasn’t been previously reported, by placing a tracking device in a rare book we suspected would be acquired by an AI company for training data, and following it around the country to its final destination. 

That final destination was an Amazon warehouse in Las Vegas, Nevada. Amazon employees who work at this location say all they do is receive massive shipments of printed books which they then cut the bindings off in order to scan the books more quickly. The printed book is destroyed in the process. The logo of the Amazon team that works at this warehouse, called VGT3, is a dinosaur, brandishing its teeth and with a book in its hands.

Twitch is going to train Amazon’s AI models on streamers’ content unless they deliberately go into their settings and opt out, potentially sweeping up a wealth of streamers who either don’t hear about the announcement or follow steps stop it.

On Wednesday Twitch announced a new setting that lets streamers opt-out of the training. The announcement confirms rumors that have percolated over the last week: It is using streamers to train Amazon’s AI models. 

The new toggle says, "Allow your channel content to train generative AI content models at Amazon." All users are opted in by default. It's located at the bottom of users' security settings page.
