Fed influences go farther than genetic "cures" for predation

Here's a thought: It's very easy for information to get "lost" during the transfer from one medium to another. The Feds could have purposely erased a lot of knowledge just by convincing new members to convert their stored data to the new personal pads they gave them. A little bit or bite here and there with each software update over a few centuries and who would notice? Might be a good idea for a story: Someone in contact with the humans sees there are holes in their own knowledge and goes in search of older, forgotten, storage mediums and finds a stash of books in someone's attic, or basement, or locker, etc. At which point they realize 'holy crap, we KNEW this stuff!'
