In this episode, we talk about the digital revolution: how can digital technology and artificial intelligence help the energy transition? How are they revolutionising energy distribution and the industrial sector? To answer these questions, we must first understand these technologies and the challenges of managing digital data, which can be an effective tool when widely accepted. These are the subjects tackled by Étienne Klein, a physicist and philosopher of science, and Françoise Soulié, a computer scientist specialising in artificial intelligence, in Ça change tout, with journalists Thierry Guerrier and Yolaine de la Bigne.
