Abstract
Technological imagination and actual technological achievements have always been two very different things. Sudden and unpredictable events always seem to intervene between our visions regarding possible futures and the subsequent concrete realizations. Thus, our ideas and projects are continually being redirected. In the field of naturoids—that is, artificial systems designed to simulate certain features of natural ones—the above-mentioned tendency is particularly frequent and illuminating, giving all prophecies a flavor of fiction rather than of reliable technological forecast. The dream of reproducing complete natural systems—man included—by means of technological strategies clashes with the “nature” of artificial objects and also with that of natural exemplars. The only certainty is that the future will exhibit growing rates of variety and heterogeneity, and we cannot know, from our present standpoint, what this will imply for our species, or, at least, for our cultures.
