I personally believe if you love technology and have got any free time you should learning Machine Learning. It has amazing applications throughout the computing industry and I believe it will be a multi-billion dollar industry in the very near future.
There is great Youtube channel called "Two minute papers" ( link: https://www.youtube.com/user/keeroyz ) where you can check out the awesome applications of Machine Learning.
I'm currently doing a Specialisation on Coursera on Machine Learning. Check it out if you are interested. The only requirement before you take this course is Python programming knowledge.
