Reading this it looks like the brain has the ability to discover and integrate memories that exist within it but may not have been organized or indexed properly. The analog I draw is if you were to insert an SD card into a computer and it reads and indexes everything it finds on the card so that from that point on you can retrieve all the files on the card just like the rest of the computer.
Now all you need is a way to "inject" pre-formed memories into people, and you would be able to learn a language, or memorize an encyclopedia, or become a doctor instantaneously.
Well, maybe. Skills are not necessarily the same thing as memories. Memorizing anatomical and surgical manuals will not give you a steady hand or a deep understanding of how much pressure to apply to make a millimeter-precise incision.
