As a graduate in artificial intelligence and machine learning I can tell you that machine learning IS hard. Sure, the basic concepts are easy to understand. Sure, you can hack together a program that performs quite well on some tasks. But there are so much (interesting) problems that are not at all easy to solve or understand. Like structural engineering it is easy to understand the concepts, and it is even easy to build a pillow fort in the living room, but it is not easy to build an actual bridge that is light, strong, etc.
