Frankly, I find the neuroscientist that pretends that we have no clue as to why we sleep to be far more obnoxious. While we don't know the full picture, we have plenty of knowledge of things that sleep is for. I did a neuropsych degree in the early-mid 90s and worked as a sleep tech in the late 90s - we knew certain things then, so it's pretty obnoxious to have this guy come along 20 years later and pretend it's a great big mystery. There's definitely stuff we don't know, but plenty of stuff we do.
