One of the great example that I know about an AI is its application in the Pharma science filed in the research laboratory. The computers there are so so powerful that they can actually form the great decisions to help and support the research scientist over there. The out puts are based on the human input and they are far better than the human research. This is giving advance chemistry field more accurate results and we can now form complex pharmaceutical molecules at glance. Considering this fact, I would like correlate this with the blockchain technology where we can use it to increase the power of AI. I mean that would be such great example in all time future ! The speed and accuracy of the AI can get multiplied by block chain and also it will be smarter to work through decentralised nature accessing the data all over the world repository. Thats just speculation but feel it!
