Medicine, biology, economics, finance, sociology, sport, the fields to mobilize machine learning are increasingly numerous. Their interest has grown steadily in recent years as they have seen “artificial intelligence” methods as technical tools for processing large databases with a high degree of accuracy rather than as a competitive science. Belatedly, lawyers are exploring artificial intelligence, but not without resistance. Sometimes considered as the dawn of a new era of “big data,” others denounce artificial intelligence in which they foresee a mechanization of the law where the machine would supplant the human. Yet, as with all other sciences, algorithms are powerful tools for knowledge production. Cooperation between artificial machine intelligence and natural human intelligence will strengthen our understanding of legal mechanisms and their application by legal professionals.
