Bill Gates' Brain Is Like a Series of Components

Melinda Gates says she feels like her husband's brain is a series of compartments. Maybe he compartmentalizes the knowledge a little bit with the book, right? And that he needs to be able to recall the book to record the knowledge. This is also where some of my frustration with the documentary comes out. I don't want to hear so many other people telling me about Gates reading a lot. What does he think about this?
