Never before has the future reached so many people so quickly and in such an extreme fashion. If you ask how this came about, words like digital revolution, networking or big data abound. What lies behind all these precipitous upheavals is rarely mentioned: feedback systems. But even those who know the word haven’t yet understood how much feedback loops have changed all areas of life — and continue to do so. With real-time communication via smartphone or tablet, the digital revolution is nowhere near completion. Nothing can escape being tracked these days, neither social relations nor political systems. Robotics, VRtechnology and 3D printing are enabling new industrial production methods.
