You’re about to give a series of talks on the history and explosion of AI. Who is your favourite fictional robot?

I guess the robots in general from Isaac Asimov. He came up with the three laws of robotics, which are basically that a robot has to obey a human, it can’t harm itself, and it can’t harm another human. My favourite robot is one [from Asimov’s The Bicentennial Man] that served a family for many, many years – in fact, generations – and eventually became human.
