In science fiction, the promise or threat of artificial intelligence is tied to humans' relationship to conscious machines. Whether it's Terminators or Cylons or servants like the "Star Trek" computer or the Star Wars droids, machines warrant the name AI when they become sentient--or at least self-aware enough to act with expertise, not to mention volition and surprise. What to make, then, of the explosion of supposed-AI in media, industry, and technology? In some cases, the AI designation might be warranted, even if with some aspiration. Autonomous vehicles, for example, don't quite measure up to R2D2 (or Hal), but they do deploy a combination of sensors, data, and computation to perform the complex work of driving.
