21st Century Cyborg?

The marriage of machine to man may create a form that exhibits characteristics beyond those capable of man. Science fiction holds examples of these in abundance, from James Cameron’s Terminator [The Terminator, 1984] to Ridley Scotts’ Deckard [Bladerunner, 2007 [final cut]].

How does a transference of such fusion sit outside of the fiction arena?

Is the ‘fusion’ itself enough in terms of a valid definition of cyborg? Perhaps even the term ‘fusion’  is subjective. Who decides to what extent the machine enfolds into the man and vica versa?

Is ‘use of’ the machine sufficient?  Or in the realisation of a cyborg definition do we tiptoe down the eXistenZ route of becoming the machine and the machine becoming us?
