The way humans store and exchange information has come a long way from cave paintings.
From papyrus to Cloud storage, centuries upon centuries of innovation has transformed data from the tangible to digital sphere, accessible by anyone, anywhere.
Scientists are already paving the way toward the future by biologically engineering data into DNA sequences.
The future may also lie in quantum storage.
If the tech industry manages to keep up with Moore's Law, a rule of thumb that has driven engineers to double computing power every two years, transistors in computer chips will reach the atomic level and be as small as electrons.
If this holds true, by 2020, information will reside in the world of quantum physics.
