When we hear about artificial intelligence, we often think of language models like ChatGPT, computer vision, or humanoid robots. But there is a branch of AI less known to the general public, which has been influencing our daily lives for decades: Fuzzy Logic.  An unappealing name, but a fundamental technology. Behind the automatic transmission of your car, the autofocus of the camera, or the intelligent climate control systems, there is often it: fuzzy logic. What is Fuzzy Logic? Fuzzy Logic, or “logica fuzzy,” is a mathematical system developed to handle uncertainty and imprecision, introducing the idea that something can be true only in part. Unlike classical binary logic (true/false, 1/0), fuzzy logic allows for degrees of truth. For example: saying that a room is “warm” does not imply a fixed temperature, but a fuzzy range – exactly how a human being reasons. Invented in the 1960s by Lotfi Zadeh, it struggled to establish itself in the United States, despite being born there. As recounted during a panel of the AI Week 2025, American culture does not align well with “fuzzy” concepts, while countries like Japan have been able to leverage its potential more quickly and widely. From the abstract to practice: where you use Fuzzy Logic every day Many are unaware that the applications of fuzzy logic are already around us: Automatic transmission of the car: every time an automatic car decides when to change gear, it does so thanks to a chip that uses fuzzy logic to interpret speed, slope, pressure on the accelerator, and other factors. Cameras and smartphones: the frames that appear in the viewfinder when you take a photo? They use fuzzy logic to automatically focus on different areas in an “intelligent” way. Air conditioners: advanced climate control systems use fuzzy logic to dynamically adapt to…
