Right off the bat, the opening scene at the bar just doesn't live up to what ended up on the screen. The images of words and numbers blurring together set the tone. That's Will's world, "flipping through a book at about a page per second."
In contrast, the closing image of Will driving to California is the perfect companion to the opening, showing us the change. As Sean points out earlier, the people who truly challenge him -- philosophers, dramatists, poets, mathematicians, etc -- are all dead. He's moving on with his life, searching for intimacy.
