Futurist and inventor, Ray Kurzweil, speak at the Newton Free Library on Tuesday, April 16 at 7PM at the official launch of his newest book, Danielle: Chronicles of a Superheroine. He’ll explore his vision of “an extraordinary future where our brains are connected to the cloud, we have hybrid biological/nonbiological thinking, our human intelligence is enhanced a million-fold, and everyone has the power of ideas to solve the world’s grandest challenges.” Danielle, the superheroine of the book, has a level of super intelligence and also “courage to question the assumptions that limit imagination.” The event is appropriate for ages 12+.
