The high number of documents as well as bodies created to deal with “the ethics of AI” leads us to wonder why AI has recently become a particular object of attention and which ethics is at stake. Starting from a review of international documents and recommendations, we will highlight issues with the vocabulary used, misleading postulates so as tensions and paradoxes. As an example, we will particularly focus on the “human control” principle. We will then insist on the risks of misuse of ethics and the need for a true ethical reflection going with AI research so as with design and use of AI systems.
