The only real argument for monolithic systems was performance, and there is now enough evidence showing that microkernel systems can be just as fast as monolithic systems.

With the subsequent strong support from cybernetics, the concepts of systems thinking and systems theory became integral parts of the established scientific language, and led to numerous new methodologies and applications -- systems engineering, systems analysis, systems dynamics, and so on.

Critical systems thinkers like Gerald Midgley identify three waves of systems thinking over the last 50 years or so. Early systems theorists (e.g. Bertalanffy) described systems in physical terms, resorting to metaphors from electronic computation or biology. This 'hard systems' tradition still has its advocates and practitioners... Subsequently the limits of the physical metaphor... were reached, and the secondwave of systems thinking developed. This 'soft systems thinking' employed social metaphors to develop appropriate systems approaches for human systems. The move to a more phenomenological, interpretative understanding of human systems, where meaning is central and is negotiated intersubjectively, parallels the new paradigm / crisis of social psychology of the 1970s. The Third wave, or critical systems school, in which Midgley locates himself, has drawn on the critical theory of Habermas, particularly in relation to theories of knowledge and of communicative rationality, and on the work of Foucault and followers on the nature of power.

We are not pursuing research to develop ABM space systems. There are studies to improve systems of warning against a missile attack, communications and navigation systems and to develop ground-based ABM defences.

Prediction of the future is possible only in systems that have stable parameters like celestial mechanics. The only reason why prediction is so successful in celestial mechanics is that the evolution of the solar system has ground to a halt in what is essentially a dynamic equilibrium with stable parameters. Evolutionary systems, however, by their very nature have unstable parameters. They are disequilibrium systems and in such systems our power of prediction, though not zero, is very limited because of the unpredictability of the parameters themselves. If, of course, it were possible to predict the change in the parameters, then there would be other parameters which were unchanged, but the search for ultimately stable parameters in evolutionary systems is futile, for they probably do not exist... Social systems have Heisenberg principles all over the place, for we cannot predict the future without changing it.
