One consequence of thisposition is a more radical understanding of the sense in whichmateriality is discursive (i.e., material phenomena are inseparable from theapparatuses of bodily production: matteremerges out of and includes as part of itsbeing the ongoing reconfiguring of boundaries), just as discursive practices arealways already material (i.e., they are ongoing material (re)configurings of theworld) (2003: 822).Brought back into the world oftechnology design, this intimate co-constitution ofconfigured materialities with configuring agencies clearly implies a very differentunderstanding of the ‘human-machine interface’.
