Artificial intelligence – AI – was a mere computational theory back in the 1950s when Alan Turing designed the first Turing Test to measure a machine's intelligence. Today, AI inhabits consumer electronics in the form of Siri, Cortana, Alexa and Google Assistant – it lives behind our internet browsers, within the relative confines of wireless networks and circuit boards. We interact with AI all the time – Google's auto-suggest function, customer service bots and YouTube's search algorithm are all examples of AI. In just half a century, AI's role in society has become firmly established. Developments in software programming and IT have facilitated important innovations in AI.
