This is from John McRuer. His addr is at end. I am exploring doing some cooperative work with him, & think he is at the forefront of pragmatic wholesystems analysis. Steve FUTURIST ARTICLE: Technological Forecast The following is an exchange between me and Bill Halal, lead author of an article containing a detailed technological forecast in THE FUTURIST. I should have added two more constraints on technological evolution and diffusion: (1) the burden of infrastructure required to support the technology and the associated risks associated with mega-failure, and (2) the politics of "central dependence" on pervasive infrstructures that require monolithic institutional control (such as telephone systems). Halal, like most of THE FUTURIST's authors is a technological optimist. His faith in John Petersen's claim that an energy revolution is about to tap the latent energy of space is not supported by the evidence.
