The most important thing is this: You pick a problem you want to solve, you pick the tools you want to solve that problem with, and one of the tools in your bag of tools is deep learning which you may end up using. Do it in that order. Do not pick deep learning and then try to solve everything with deep learning, that's putting the cart before the horse. That's all I can say about things like deep learning, blockchain, etc. Let the problems lead you to the solutions, not the other way around.
