Digital footprint

Nowadays, almost every act of human interaction with the outside world leaves a digital footprint. By our actions, we bend the digital space, excite it. In the context of historical science, trace is an important epistemological concept associated with any source that contains information about us as humanity. But will our footprint be commensurate with eternity, or will a gust of virtual winds sweep it off, making things go back to the way they were?
