In the late 1960s, however, there was a backlash. Klaus and other cybernetic philosophers started to be accused of trying to replace Marxism-Leninism with cybernetics. Party elites worried that a cybernetic communism would erode the authority of the party, a theme that was also seen in the USSR's rejection of cybernetic communism. (To be fair, some technocrats joked that their computer for modeling the economy was "the guillotine for functionaries" so that fear was probably justified.)
