That is so silly. Can you give me one documented, verifiable "instant learning" of a complex subject example that's not an unverifiable anecdotal account?
Some things just don't happen in the real world. Like talking donkeys...
No one in the real world could learn a new and complex language in a very short time, say a week, but one man did. He learned the Icelandic language in one week, ONE WEEK, and even made jokes playing upon the peculiarities of the language. One week.
But things like are impossible!..... like falling thousands of feet to the ground from a plane and surviving. Not in the real world!. some things just don't happen!
