I refuse to say anything beyond five years because I don't think we can see much beyond five years.

As soon as you have good mechanical technology, you can make things like backhoes that can dig holes in the road. But of course a backhoe can knock your head off. But you don't want to not develop a backhoe because it can knock your head off, that would be regarded as silly.

In the brain, you have connections between the neurons called synapses, and they can change. All your knowledge is stored in those synapses. You have about 1,000-trillion synapses - 10 to the 15, it's a very big number.

I think we should think of AI as the intellectual equivalent of a backhoe. It will be much better than us at a lot of things.

To deal with a 14-dimensional space, visualize a 3-D space and say 'fourteen' to yourself very loudly. Everyone does it.

In science, you can say things that seem crazy, but in the long run they can turn out to be right. We can get really good evidence, and in the end the community will come around.

I think people need to understand that deep learning is making a lot of things, behind-the-scenes, much better. Deep learning is already working in Google search, and in image search; it allows you to image search a term like "hug."
