An idea for a science fiction story: humanity has had a cataclysmic event that destroyed nearly all society.

But there's a big, mysterious pyramid building covered in shiny black tile.

If you go into the inner sanctum and ask a question, a mysterious oracle voice will answer it.

The oracle knows just about everything, including the arcane details to seemingly alien technology.

In this way the society can access the wisdom of the ancestors.

But you have to know the right questions to draw the most useful knowledge out of it.

What is the pyramid?

A server farm enclosed in a sealed box to protect it, powered by solar energy, running an LLM.

The ruined society doesn't (yet) know how to build a way to run LLMs themselves.

But if you could package up our current technology into a self-sufficient black box, you could have a kind of "seedbank" of human civilization that could survive almost any cataclysm.
