In 1950, British mathematician and cryptanalyst Alan Turing introduced the idea of a test to see if a machine could be indistinguishable from a human. Promptly dubbed the Turing Test, a passing grade is the holy grail of artificial intelligence. Think of the Voight-Kampff test in Blade Runner. Except at the end, you don't shoot a replicant. Yet. In its current incarnation, the human judge sits down at a computer and begins texting with an unseen partner. Being unable to see who they are talking to, the judge must rely on conversation cues to decide whether their partner is human or machine. Turing famously predicted that by the year 2000, a computer program would be able to convince 30% of people that it was human. The event organizers used this prediction—taken somewhat out of context, as Turing never set any specific guidelines for what a Turing Test should be—to set the win conditions of the Turing Test.
