Here's a link to the Kiwix library download for all of Wikipedia. It's 111GB though, so you'll need a lot of space and also a lot of time to wait for it to download.
Note, you'll also need Kiwix in some manner to read the zim file once it's downloaded.

But this'll let you have a local copy you can reference should actual Wikipedia ever get ruined by GenAI, or worse, get taken down by hostile governments.
