according to gerovitch, by the 1970s, the "tactical uses of cyberspeak overshadowed the original reformist goals that aspired the first soviet cyberneticians." the ideas which were once seen as controversial, and huddled under the umbrella organisation of cybernetics, now entered the scientific mainstream, leaving cybernetics as a loose and incoherent ideological patchwork. some cyberneticians, whose dissident styles had been sheltered by the cybernetics movement, now felt themselves persecuted; cyberneticians such as valentin turchin, alexander lerner, and igor mel'čuk felt the need to immigrate to escape this newfound scientific atmosphere. by the 1980s, cybernetics had lost its cultural relevance, being replaced in soviet scientific culture with the concepts of 'informatics'.
