Alphago is shocking

I have watched the previous two games, and the result is really shocking. AI + deep learning has pushed machine learning technology to a brand new level. We can hardly use the old mind to think about AI anymore. AI is just like a high speed moving train, when it hasn't arrived yet, we can only hear its sound and expect it can come sooner, but when it did arrive, you can hardly see the appearance of its body, and it just leave you far far behind it. Maybe one day we all gonna regret what we do to contribute to deep learning or AI today. But that's the price we have to pay for our curiosity.
