I 'm not even sure why it provokes such reaction. Neural networks have existed for 4 decades ; without the deep- part, but we know their potential power and we still have not been replaced. Granted, this time it's different. I think what worries most of us is that neural nets need lots of data and we don't have access to it. Still, they are easy to learn and we should be learning about them (note to self).
