You're putting textbooks together from loose pages by reading the numbers on the pages. Each time you finish one, you give it to the publisher, that photocopies it and sends it to the schools. Some pages from other books ended up in your boxes of pages. It's easy to tell if they don't belong there if they're the wrong size, different font, different color, etc. Some pages have typos, but if they end up in your book, it doesn't necessarily hurt anything. Unfortunately, some of the pages have bad information on them. They have the right number, they fit in the book, but what is written on the page is totally incorrect. If you accidently include one of these pages, the next generation of students are taught bad information. If this information was really important, like building code or growing crops, and the next generation of students start building and farming wrong, society falls apart.

Prions are the bad pages.

Oh shit, I just realized AI summaries are prions.
