With GPS systems and other geographical technology being as sophisticated as it now is, do lighthouses still serve an integral purpose? Are they more now just in case the captain/crew lapses on the monitoring of navigation systems? Obviously lighthouses are more immediate and I guess tangible, but do they still fulfil a purpose beyond mitigating basic human error?

What do you do when your fancy technology fails? You want backup. So many people rely so heavily on their GPS, phones, computers, etc. that they have no idea how to read physical maps, use a card catalog at a library, do math long hand, cook food etc. These are the same people who would be absolutely helpless in a catastrophic event because they couldn’t feed or shelter themselves much less fight off the zombies.
