For the uninitiated, the arguments for and against these sex dolls are complex. For example, some people fear that doll robots may harm marginalized sex workers, while others may see the advent of TPE dolls as a way to keep these workers safe.

This view has been repeatedly challenged by sex workers themselves and by organizations such as Amnesty International.
