Nearly 3,000 years ago, the philosopher-mystic Pythagoras claimed that everything can be expressed in numbers. At that time, no one understood him. Today, we are witnessing a digital breakthrough in which machines analyze large amounts of data on decisions made by people in different situations, translate learning algorithms into their own language, and act by analogy with humans. Today, developments in the field of AI and Machine Learning confidently follow the path of creating a computer, the cognitive functions of which are comparable to the human brain. The areas of finance, banking and insurance are the most promising areas to apply these technologies.
