We should keep some people around who can read paper maps (and keep paper maps around too). We need to keep doctors around who can keep working without a computer. It's a civilization threatening issue not to. There might be plenty reasons, from natural disasters, to self-inflicted "geopolitics", when we suddenly have to take a technological step back, and it's in our interest to maintain "30-50 years ago" level of tech possible, so that we don't have to start all over from something resembling a bronze age.
