Brains working towards machine consciousness

Dave White wrote about his Digital Resident/Visitor model on the TALL blog back in 2008 (http://tallblog.conted.ox.ac.uk/index.php/2008/07/23/not-natives-immigra...) and it has been well received. I have recently been thinking about the Digital Native/Immigrant idea of Prensky again, and finding a lot of the criticism of it to be focussed on a particular point, and somewhat lacking in critical reasoning, so I thought it about time I went back and looked at Dave White's model too.
