Our civilization has rapidly entered a new stage of development. It's the 4th industrial revolution. This is the epoch of automatization, internet, and data exchange in manufacturing technologies and processes which include cyber-physical systems (CPS), IoT, industrial internet of things, cloud computing, cognitive computing, and artificial intelligence. Basically, we start using some form of AI algorithm since we start walking. It's already an integral part of each developed society in the world. Windows, macOS, Google, YouTube, Facebook, Instagram, etc., all our operating systems, search engines, and applications are using some kind of machine-learning algorithms. But what do we know about them? Is it safe to continue developing and improving AI systems? Given the fact that an AI algorithm can collect and elaborate upon tons of data in just seconds maybe we can try to learn something from them in return.
