All right. I found it. I’m not conceding my earlier point. I think not being able to search audio and video files for something someone said instead of something someone wrote is going to become a bigger problem as we continue to explore using these media online.
The audio I was looking for, incidently, was from Marc Prensky’s keynote speech at the Christa McAuliffe Technology Conference in Nashua, NH in November, 2005. This speech was recorded by Bob Sprankle and posted as part of his Bit by Bit podcast (episode 18).
The comment about kids using email mostly when talking to their parents came about 27 minutes into the first part of the speech.
