I think cyber security is going to be huge too, but not sure how to make a play on it, don't see any obvious winners in the security space. What approach do you take?
If I knew the next Bitcoin I'd definitely have typed it out. Sometimes the answer is to just wait and see and let your thoughts kinda work through things. What I know for sure is that there are a lot of powerful people that found out how important cyber security is in the past couple years. Snowden, Clinton, Paradise Papers. The market will do its best to try to meet this need.
The need for very seasoned professionals who have BOTH security and heavy development/business/architecture backgrounds will be a scarce thing.
