It not about how smart future people will be, or how we can eliminate every danger possible for future man. It is that we even today we do not reference old documents to figure out what is safe and was is not. As an example, humanity has documented ocean dangers for centuries. Everything from human created dangers like shipwrecks to natural occurring shallows and strong currents. Captains that want to avoid those dangers could read those, learning every language from ancient Greek to Latin to dutch, scouring the many archives that exist to figure out what is down below. No one does this (except for archeologists). Captains use modern maps, sonar and satellites, neither which require knowledge of ancient Greek. Maps and their information about dangers are perishable with a fairly short lifespan. Making a map with the intention of it lasting hundred of thousands of years is an impossible task. Any danger, be that natural like cliffs or unnatural like mine shafts, can not be made into a map that will last hundred of thousands of years. Such maps will need to be maintained or rediscovered. Every single garbage dump, every industrial area, every zone or place where humans has done something to the environment will have to be maintained in updated maps for as long as those places remain dangerous to humans.
