Studying cutting-edge technologies in the domains of medicine built by Tanzanian experts operating on the margins of global techno-science has often led me to fall into a Manichean outlook. That is, seeing these processes in which technologies are built from rather than merely for the country, as either dispiriting evidence for another technological fix or as an encouraging sign pointing towards the building of new sovereign techno-science futures. Given our own expertise as social scientists, we are expected not to succumb to such binary reasoning and develop more sophisticated approaches. In this Position Piece, I propose that given the doggedness of such binaries that I suggest we might all be liable of falling into, we should work hard to develop a curiosity and reflectiveness about our own judgements and the process of making them.
