Before we know it, artificial intelligence will be all around us. Are we ready?

Black and white photo of astronomers Clarence Chant and Reynold Young kneeling and sitting, respectively, on the ground. Young is looking through the eyepiece of a long cylindrical-shaped camera positioned perpendicular to the ground and attached to a square tube covered with a cloth-like material. Chant is holding a black rectangular board underneath the tube.
