The sociological understanding of technology has made great strides in the past two decades. One sign of this is the fact that today there is no need to begin an article about technology with a disclaimer of ‘technological determinism’. It is taken as given that technology is not a prime mover, that it is socially shaped, a suitable case for treatment by social science. Another claim, however, cogently argued over the same period, has not yet become an accepted proposition in mainstream theories of technology. This is feminists’ claim that the social relations of technology are gendered relations, that technology enters into gender identity, and (more difficult for many to accept) that technology itself cannot be fully understood without reference to gender.
