Brown's straightforward presentation using old school tools (lecture, powerpoint) still manages to get across the message:  we are not in Kansas anymore, Toto.  Our institutions and our social rules are epitomized by change.  In fact that is there only constant.  Yet our schools at almost every level seem to be enmeshed in some bizzaro Oz that denies the obvious--the Wizard has no clothes.  Yeah, that is shocking in black and white or color, but as Brown states our skills have a half-life of five years.  This video is a lodestone attracting and evoking lots of ideas for learning in general (the mob does indeed rule) and pedagogy (tech teaching especially) in particular.  I would love to watch this with folks on a Google Hangout one night and see what comes of the conversation.  Up for it?  Let me know at Twitter: tellio or Google+: terry.elliott
