It turns out that we’re not the only ones talking about MIT psychologist Sherry Turkle, our Symposium keynote speaker. Her new book, Alone Together, an insightful look at our shifting relationship with technology, has gotten a lot of press recently, earning glowing reviews from both Newsweek and Time.

Have you ever text messaged someone who’s in the same room or e-mailed people in your office rather talking face-to-face?

This week, she appeared on the Colbert Report to discuss it.
