The world has started developing AI from very longtime .... anything you want a computer to learn it by himself must include machine learning and artificial intelligence algorithms.
Simple things you see everyday doing that is your own PC...for an example on facebook every time you put a photo , facebook starts learning and detecting your face so after some time("photos you have been tagged to") it will then suggest automatically your name and your friends name next time you add a photo and tag it.
Not just facial recognition and facial expression.Also Ads showing on your browser .. most of them will be related for something you had searches for and tons of things now are working with (AI, Machine learning , computer Vision)
all of those are branched from "Data science".
this video here will explain what google had made.
Hope you enjoyed :"D
