Joseph Weizenbaum considered that not every part of the human thought could be reduced to logical formalisms and that “there are some acts of thought that ought to be attempted only by humans”.[14] He also observed that we develop emotional involvement with machines if we interact with them as humans. When chatbots are anthropomorphized, they tend to portray gendered features as a way through which we establish relationships with the technology. "gender stereotypes are instrumentalised to manage our relationship with chatbots" when human behavior is programmed into machines.[15]
