Of heroes and butterflies: Technological dreams and human realities

Abstract

Since the seventeenth century the dream of rendering human life less arduous and of securing it against the whims of fate through the development and deployment of technological devices has been a factor stimulating scientific research and development. This dream rests on a supposition that we live in a universe governed by deterministic laws in which limits on our ability to predict and control are set only by the imperfection of our knowledge and skill. But recent work in chaos theory combined with reminders that human beings themselves form part of the worldin which they live and seek to control suggests that this supposition is unjustified. If this is the case, then the idea that there is a technological solution to every problem, one which can be found by scientists or experts (the modern heroes) is revealed as a magical attitude which should have no place in rational decision making and whose persistence threatens to turn scientists into the high priests of a cult of technology.
