It is realistic to the extent that the physical network shares the same network properties of the virtual/Internet network. According to Steven Johnson, innovation works on having a platform (which stakeholders eventually "buy into" and adopt) and the liquid network that forms around it. So eventually the feasibility and propagation of an idea depends on "buys" at two levels:the common platform and the informal exchange of ideas that the platform facilitates. An inappropriate platform can actually choke the liquid network of ideas OR the liquid network of ideas has no roots or grounding in any platform, and ends up floating around like a phantasm.
A more technical treatment of this is to ask ourselves:"what technology is"- is it the platform?Is it the liquid network? And how does technology evolve?
