Good content, however I'd have preferred "You Are A Mind" or similar. You are an emergent system centered on the brain and influences upon it, or somesuch. It's just that "brain" has come to refer to 2 distinct entities -- the anatomical brain, and then the physical system generating your self. The two are not identical.
Here's a 32-minute presentation I made to provide an introduction to some of the core LessWrong concepts for a general audience:

I already posted this here in 2009 and some commenters asked for a video, so I immediately recorded one six years later. This time the audience isn't teens from my former youth group, it's employees who work at my software company where we have a seminar series on Thursday afternoons.
