Abstract <p>We present the current state of quantum mechanics, the prospects for its development, and the strengthening of its influence on scientific and technological progress. We look at quantum mechanics from four perspectives. The first perspective astonished physicists already with the advent of quantum mechanics—it is (1) a new way of looking at the world. Over the course of a hundred years of development, quantum mechanics has acquired three more perspectives: (2) an independent field of knowledge, (3) a new physical theory, and (4) a radical change in paradigm in the history of human thought. We have named the new paradigm “neo-Copenhagen” to emphasize both its development from and its continuity with the Copenhagen interpretation. We review the problems of quantum mechanics: how experimental research progresses, how basic concepts develop, how practical applications of paradoxical ideas expand. We indicate ways to solve three Ginzburg’s “great” problems. We formulate the features of the neo-Copenhagen paradigm that have already emerged. We present a look at the future of science and technology on the three time scales.</p>
