UC Berkeley Professor Smashes His Laptop in Front of Students to Make a Point About Expectations

From Youtube:
On the first day of my Critical Making class at UC Berkeley, I wanted to make a point about expectations – about expectations for this course and more importantly about leaving them behind as we enagage in the material and topics within Critical Making. Rather than say it or even show a slide, I unexpectedly and dramatically lifted “my” laptop and smashed it across the floor of the classroom.
