You can't wake up knowing new information. Everyone has to learn, the people who look talented just learned it earlier than everyone else.

Of course you are correct that the "naturally smart" people learned it faster. As in, new information was provided to them just once or twice and they instantly grasped it and were able to apply it.

As knowledge accumulates in people they may also actually "wake up with new information" nobody taught them. As in their brains may make associations and conclusions without someone teaching them. The proverbial "I had an idea while showering". There's your "talented" guy.
