"The idea that neural networks will learn everything, that you don't have to program stuff in, except for the learning algorithm and but all the content alone, was regarded completely crazy by most people in AI. It's still regarded crazy by many people but it's now being accepted because it works. So, it's sort of mainstream crazy." — Prof. Geoffrey Hinton
In the following short interviews Geoffrey Hinton explains how pervasive the neural networks and deep learning are becoming in the following years. And how it will change the world.
For more interested reader I recommend this 20 minute presentation by Geoffrey Hinton about how neural networks really work.
