The article discusses the theory of technical evolution by Doug Engelbart in the US. It is not well known that Engelbart has his own theory of technical evolution, a theory which mobilizes technology as its own milieu that evolves in tandem with human socio-cultural and language practices. The aspect of his theory could be seen as a form of technological determinism. According to the beliefs of Engelbart, the tool system currently moves faster than the human system and it takes generations before one can develop the appropriate human infrastructure to deal with changes.
