Different kinds of technologies are said to have limits, problems, drawbacks. However in some or most cases there are limits of the technology itself but limits of our own neocortex. As an example, according to the social scaling idea from Nick Szabo, the result of the institutional systems in the trust based services is the direct result of our neocortex is able to handle at most around 150 social connections. Probably, our love for the different hierarchical structures is the direct result that our neocortex is organized in a hierarchical way.
