For the past several millennia, all societies have developed because they had access to their information, and the knowledge developed therefrom was equipped with sustainability (long-term and continuous access).

With the arrival of the Internet, the situation has changed because digital media is currently rather weak and unstable :

Big Data

Our society’s administrators have placed bets on the belief that our flows of information will last a long time, which is not the case.

With age, tapes decompose, hard disks must be renewed, video discs become unreliable, versions of encoding languages ​​disappear while we develop even more devices to process text, images and sound.

After 2020 (?)

We have begun to search for new solutions :

  • In the short term, development of cloud computing with correcting codes.
  • In the long term, Japanese researchers are seeking more stable support and have turned to quartz (Kyoto University, Laboratory of Hitachi, etc.)
  • Also in the long term, we want to replace the binary system (0 and 1) by DNA genetic code that has four states (ACTG), see European Bioinformatics Institute in England.
