In recent centuries a relative handful of brilliant people have devoted their lives to figuring out some very difficult things and developing some ingenious tools to do so along the way. However, as far as I know, the only places this work has been recorded is on things that are easily destroyed - paper, hard-drives and human brains. None of those things will stand the test of time. One natural disaster and all this progress could be wiped out in one fell swoop (which is obviously not unprecedented), leaving future civilizations having to rediscover things from scratch. Then you look at what archaeologists have found that have taught us about the past, stuff that has lasted tens of thousands of years. Stuff made out of much more durable materials. Shouldn't some committee be looking to make a more permanent record in the same way? Or is this being done already? I'm aware that a future civilization might not speak any language that exists today, but perhaps that could be overcome, if a language/alphabet came with diagrams of how to form certain sounds with your mouth or something. What do you think?
