Dr. Christof Koch, Chief Scientific Officer, Allen Institute for Brains Science, wrote a recent blog post for Nature entitled "Lust and the Turing test."

"By and large, we watch movies to be entertained, not to be provoked into deep thought. Occasionally, a film does both. This year’s Ex Machina is one such gem. It prompted me to reflect upon the evolution of the idea of machine sentience over the past three decades of science fiction on film.

I am a long-time student of the mind-body problem — how consciousness arises from the brain. There is a conundrum at the heart of this ancient dilemma, challenging both brain science and AI; and it is well captured by Ex Machina and two other SF movies. In essence, it lies in how we can ever be certain that a machine feels anything, is conscious."
