I would also put all the classic sci fi books from The Foundation and Dune series to cyberpunks such as Snow Crash, Cryptonomicon and Neuromancer in there as well. Also would add my fav Lord of the Rings and Hobbit book series in there.

Great list.

Perhaps a stupid question - does that Wikipedia number include photos? If not, what kind of overhead does that add?

That would be the Wikidata Wikicommons dataset. It's 375 TB (source: https://www.wikidata.org/wiki/Q565 ). Including also audio, etc...

Thanks. That makes me feel silly...I had no idea so much media existed on Wikipedia, nor that it had enough text to fill that many GB alone.

English Wikipedia is only about 89GB with pictures included and 46GB without.

I've maxi version with images on my Pi and it works locally without internet access. I've also backup in a faraday cage.

> If I had only one floppy disk, it would be a selection of philosophy books from Socrates, Aristotle, Marcus Aurelius, Thomas Aquinas, La Boetie, Kant, Spinoza, Descartes, Nietzsche, Wittgenstein.

Only western thought is valuable

Biggest scam. Remember when growing up history would just skip Africa making you think tribal wars that's it.

Musicians channels playing music styles from around the world but skip Africa

But time have changed they are telling their own story...

I would rather go with medical and survival information rather than a bunch of philosophical ramblings or stephen king novels tbh, given the above scenario.

Also anything practical how to build stuff, how to get water clean, electricity running, batteries.

> What content/knowledge is most important?

For me, its what you need to survive.

We have to make room for plenty of kitten videos though.

I hear kittens are always ready to make more kitten videos, as long as kittens survive we can rebuild those from scratch.

I recall reading somewhere in the event of an apocalypse you'd need at least ~150 breeding pairs of humans to be able to recover (I think that's with no safety margin either), and it would take generations of careful management to prevent inbreeding and genetic weirdness.

I wonder how many cats you'd need? I would think it would be much higher as I assume superfecundation would drastically increase the risk of inbreeding.
