@Gargron I'm afraid even data on physical media will be lost, unless it's text and images that can be viewed with the naked eye without the need for any technology. The Industrial Age will simply end in a huge collapse because we failed at becoming sustainable when it was easy (1970s-1980s), we even failed when it was hard, but still feasible (1990s-2000s), now all our efforts to become sustainable can only slow the decline if we're lucky. 300 years from now, everything stored on digital media will be gone. Everything printed on cheap mass-produced paper will be gone.
