Computational thinking is now taught in many higher technical courses. CT involves solving problems, designing systems, and understanding human behavior, by drawing on the concepts fundamental to computer science. In this presentation we will take a critical look at the CT approach and its epistemological foundations. I will present the paradigms on which the problem solving process is based, introduce the “Conquer & Divide” method, and illustrate the sometimes unhealthy interaction of CT with society through examples and anecdotes. I will end this critical overview with initiatives that assimilate CT in a critical gesture, such as de-computation. My wish is to generate astonishment and reflections that participants can share after the talk.
