Is it worth downloading the entirety of Wikipedia (around 50 or 100 GB depending on whether you include images) just in case? Despite being bad for sensitive and controversial topics, Wikipedia still has tons of (comparatively) unjewed knowledge, and if you have the storage space maybe it could be good to prep and have an offline copy just in case for scenarios where you can't access the internet.
Otherwise, is there some other text-based knowledge resource that could be useful to hoard? Something like a curated archive of thousands of books.
That sounds too jeety and overengineered for my purposes. LLMs are not very reliable and hallucinate a lot, and they would require/consume much more resources compared to looking at offline web pages.
Wikipedia is just too low-quality and politically biased to be useful. Perhaps a selection of articles may still have value, but I would rather download a curated archive of books as you described.
I think having a copy of Wikipedia is still useful as long as you dont read the controversial articles. Add Gutenberg library (71.6 GiB) too just in case
you'd be better downloading/obtaining other encyclopedias, preferably old printed (or scanned) ones such as Britannica as opposed to most online resources (some should still be archived, like wikispooks mayhaps) as they have less of a bias
i doubt you really need all that knowledge, you'd also do well to get more specific books on certain subjects of interest
is there a way to have a signature without looking like an attention-seeking poltroon?
for me wiki (and sister projects like wiktionary) are highly useful as a quick reference for scientific subjects (for me, math and physics mostly), word definitions and the like. I have recently learnt latex entirely from a wikibooks textbook downloaded offline.
check out the openzim format by kiwix. https://browse.library.kiwix.org/#lang=eng they have tons of wikis/forums/programming docs/textbooks etc. packaged as highly compressed files. you can use their official app to read them but ive found this one to be better https://github.com/birros/web-archives (on arch its in the aur)
A bit of a late update, but I did download Wikipedia, through Kiwix, and I also downloaded a bunch of other potentially useful resources that were on Kiwix.
Now, as malformed_jill said, I should look into old encyclopedias.
