Artificial Intelligence (AI) is enjoying one of its periodic moments in the limelight. Why this interest now? Some of this we can put down to the ongoing fascination Hollywood seems to have with AI. From Stanley Kubrick’s 2001 to Ridley Scott’s Blade Runner, Stephen Spielberg’s Artificial Intelligence to Alex Garland’s Ex Machina; Hollywood has made enjoyable films and good money out of AI.

These films have inspired generations of AI students. Indeed AI was once described as making computers that behave like the ones in the movies! However, Hollywood invariably takes a dystopian view of the subject. The computers and robots are usually mad, bad and dangerous to know. Yet this doesn’t seem to hinder AI’s popularity.
