Artificial Intelligence: What's Real and What's Not in 2017

I'm a big Star Wars fan, so when "Rogue One: A Star Wars Story" descended on theaters late last year, I braved the crowds to see it -- twice in the first 18 hours. And just like all the other Star Wars movies, "Rogue One" stoked our geeky imaginations with all the technological possibilities of a galaxy far, far away, like holographic displays and all sorts of strange devices. And did you notice the Imperial server farm? Of course, advanced artificial intelligence (AI) was well-represented too: Like C-3P0, R2-D2 and BB-8 in earlier movies, Rogue One's K-2SO displayed uncanny humanness. The futuristic Star Wars-esque world is still mostly the stuff of Hollywood movies, but technology visionaries are hard at work bringing us ever closer.
