When we speak about cosmic flights and the exploration of space today, we have in mind a dynamic model of technological progress. This dynamic model of progress implies that what we’re doing now in cosmic space will be continued and further improved by the next generation, and so on. The cosmists did not believe in this model. Their questions were along these lines: Why should we be interested in progress if we don’t stand to gain anything from it? If my generation contributes something to cosmic space, how can I benefit from it? I remain mortal, and I remain eternally indentured to progress. I live now—and not in the future. If progress is defined by a dynamic directed towards the future, everyone is yoked to progress, and every generation fast becomes psychologically and physically obsolete.
