We kicked off our summer book club last week with a discussion of what makes a good summer read. Today we discuss our first pick from Senior Producer Mary Harris. Her choice for the summer is Daniel Wilson’s “Robopocalypse.” From “The Jetsons” to “Star Wars” to “Wall-E,” robots have long been part of the American imagination. We talk to Daniel Wilson, a trained roboticist, about how “Robopocalypse” fits into this American tradition.
