 Techniques such as artificial intelligence and machine translation show a shift to linguistic and symbolic production as central elements of the postindustrial economy and the related postmodern culture, which had risen at the end of the 1950s after the reconstruction of western Europe.The result is a plurality of language-games (a term coined by Ludwig Wittgenstein), of different types of argument.At the same time, the goal of truth in science is replaced by "performativity" and efficiency in the service of capital or the state, and science produces paradoxical results such as chaos theory, all of which undermine science's grand narrative.
