Does technology affect memory?

Nowadays, we believe that technology, applied to researches, can give us a very approximate idea of what reality is, it is even capable of imagining past and future states of the researched subject. But the result is based solely upon speculation; by this I mean that technology is able to recreate almost any event in the virtual world and by means of crossing references recreate also the interactive surrounding circumstances.
Reality is so wide and full of references that it is necessary to delimitate the elements and concepts to refer to.
