Sherry Turkle’s keynote presentation at the RSA on Wednesday was a real treat for me; it was the first time we’d seen one another since I interviewed her for The Virtual Revolution in November 2009, and since she had published the book she had been working on.

Turkle’s book, Alone Together, is an intense volte face from her previous two books in the trilogy about our relationships with new technologies and our relationships with each other via these new technologies. In it she argues, for example, that communities demand a physical co-presence. Holy wow.

At the event, rather than perform her prepared presentation, she tackled a question I’d asked backstage: What Happened?
