Frankfurt, Feb 07, 2018 — The automation of production is accelerating around the world: 74 robot units per 10,000 employees is the new average of global robot density in the manufacturing industries (2015: 66 units). By regions, the average robot density in Europe is 99 units, in the Americas 84 and in Asia 63 units.
I do not know the exact number of robots currently operating (in the shadowy sense, i.e. production machines and other machines as well as human robots) in the world, but certainly in recent years and in the subsequent number of them is growing rapidly. According to estimates, in the next dozen or so years, if not before, their number may be equal to the number of people on Earth.
