Since time immemorial, humans have continued to expand their domain both mechanically and cognitively. Writing was the first way to expand human memory. With the advent of Artificial Intelligence (AI), it is not only the human ability to memorize that expands even further, but also man’s ability to reason and to handle a huge amount of data in record time. This new cognitive paradigm changes the game of being human. Medicine is undoubtedly the domain in which AI is the most advanced. Psychiatry seems to still be in the discovery phase. But for nearly fifty years, a number of projects have helped change practices, either through conversational agents, expert systems, or virtual assistants, for example. AI will also affect psychiatry, however, by providing its own pathological subjects suffering from a new type of dissociation, that of man in relation to his virtual alter ego.
