I took Geoff Hinton's Intro to Neural Networks course a few years back. After class he would have optional Q&A sessions where he would answer anything about anything. They were amazing. I think we even asked him once about his views on Margaret Thatcher. After we covered deep belief nets, RBMs, and autoencoders, I asked him if anyone was using deep belief nets in the real world. He said "no, but these results are too impressive to deny. Within a few years, they will be." Looks like he was right. Congrats, Geoff.
