This paper discusses a way to create social innovation around 2040. With such innovation, social restrictions that are regarded as being inevitable in the current society can be eliminated. First, it is necessary to determine how to approach the innovation. Symbiotic technology is one of the promising technologies for achieving social innovation. It is the fusion of scientific technology and socio-technology. Its elemental technologies are classified into two categories: technologies for converging the real and cyber worlds and those for integrating (...) hetero-systems. This paper describes examples of those technical categories and introduces the challenges of the first step toward social innovation. (shrink)
