@Em0nM4stodon When I read 110GB at first I thought it was just the text. Turns out that includes media. My mind is blown.
I was also inspired by your post to see if Khan Academy can be downloaded for offline use, and it turns out it's possible with a platform called Kolibri that provides educational resources for people or places without internet access:

Good. What about articles' edit histories and talk pages?
