The past is always disappearing. I know of no data recording device that we could use to store anything for more than a million years except DNA (for fun check out the Arch Mission Foundation that attempts to use DNA for backups of human knowledge) [0] or 5D nanostructured glass [1]. This post reminded me of a great Kurzgesagt video [2] that went briefly into how much of the past life on earth we have no information on and will never be able to know. Incidentally it took me a few seconds to find that video. Before the internet if I was trying to lookup a clip I had seen a month ago on TV I don't know even where I would have begun searching... However I think we are getting increasingly better at preserving information and making it easy to access with tools like the internet archive, and cloud backups for your photos. This is despite the sheer quantity of data (such as the number of photos you take) growing at an exponential rate. Would you have been able to easily find instructions for a machine that was decades old before the internet? So the past is disappearing but possibly at a decreasing rate. 0: https://en.wikipedia.org/wiki/Arch_Mission_Foundation https://en.wikipedia.org/wiki/Arch_Mission_Foundation 1: https://en.wikipedia.org/wiki/5D_optical_data_storage https://en.wikipedia.org/wiki/5D_optical_data_storage 2: https://www.youtube.com/watch?v=xaQJbozY_Is https://www.youtube.com/watch?v=xaQJbozY_Is
