The Doomsday seed bank
Norway’s planned "Doomsday" seed bank in the Svalbard Islands. The problem with a truly catastrophic event is that some of the seeds will last no more than a decade.  By the time it was rediscovered, many of the vault’s contents could be long decayed.
There are plans to create a training scheme for "digital plumbers" so technicians will have the skills to handle home entertainment and automation systems.
