Why are lighthouses still necessary?

1.45K views

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?

Additionally, most light houses are fully automated now. Since they’re not just an old man climbing a tower with a torch every night now it would make sense to keep them on even if every boat has perfect gps awareness.

Giving peace of mind and a solid backup plan in a storm or equipment failure is priceless.
