Freeman Dyson had a similar point in a TED lecture on the thorium nuclear reactors. He has spent a life time trying to get rid of nuclear bombs while promoting more responsible uses of the technology.

A 2009 study by Nicholas Epley et. al. from the University of Chicago reached very similar conclusions Believer's estimates of God's beliefs are more egocentric than estimates of other people's beliefs

Love the comment from RD : A computer is nothing, but a box in which electrons are whizzing about obeying the laws of physics.

Dangerous move by the A of C to hang his hat on the mystery of consciousness.

When will these people look up the meaning of the term 'militant'?

"Nothing could have been farther removed from the labeled-line model. Instead of highly specialized neurons (like the infamous grandmother neuron) that fire in response to a single stimulus attribute (e.g. the face of one's grandmother), distributed neural representations are formed by broadly tuned neurons, which convey small amounts of information. As such, any individual neuron's instantaneous firing activity, when taken in isolation, is incapable of either discriminating between multiple stimuli or sustaining any behavior. However, when large populations of broadly tuned neurons are working together, precise computations can be achieved." -Miguel Nicolelis Beyond Boundaries pg 115-16.

While the experiments showing the idea of a grand mother neuron are fascinating and beautiful they are outdated. Why we ever thought a single neuron is responsible for any one particular attribute is beyond me when you look at the brain itself; Something on the order billions of cells forming trillions of connections. Neural networks and their high interconnectivity is the beautiful symphony of the brain.
