Flashback: When AI paid chump change

The 2000 essay by Joy, then chief scientist at Sun Microsystems, was called "Why the future doesn't need us." In it, he argued that new forms of technology were potentially dangerous and could render humans obsolete. It sparked an ardent debate. One impassioned reaction was from Richard Wallace, a chatbot expert who created ALICE, the inspiration for Spike Jonze's Her, and who now works at Pandorabots. I asked Andrew Moore, dean of computer science at Carnegie Mellon University and a former VP of engineering at Google, for his thoughts on the 18-year-old comment.
