Here is what worries me. In the past when civilizations met set backs or catastrophes, their records allowed their legacy to continue. These have historically been written records on stones or vellum or something that would survive the ravages of time. But now, everything is on some sort of media that requires technology to read it. What happens if some catastrophe occurs, and the electronic devices required to read the records don’t work anymore, or nobody knows how to use them, and those records become unretreivable. Humanity will essentially have to start all over from the cognitive revolution forward. More than 10,000 years. That sucks.
