If things are so bad that you need to factor in the non-operability of any electronic devices, how many indestructible paper libraries are you planning to build and manage in advance, and at what budget?
Either way the comparisons here are unfair. An LLM that runs off a backpack-sized solar panel and a laptop might be a substitute for a broad, low quality, surface-level encyclopedia but it's many orders of magnitude worse than a library of books.
I would argue that in a survival situation the accuracy of information becomes even more important. If an LLM to misidentifies a plant (or a medical condition, its treatment, etc.) it could put you in an ER, but in a survival situation that could kill you.
If there's any place to get an answer it's here.
Bravo my friend. And I mean that in a good way. Love me some diversity.
