Cool pet project, admirable engineering etc.
My comment is about something else: net neutrality, as someone already mentioned.
I was teaching English in Laos for school kids. I was amazed that some of their families struggle with providing (nutritious enough) food for their children, yet, everyone had smartphones with always-on 4G,even in the countryside - however, no WiFi almost anywhere.
The brains of these kids are like sponge. They WANT to learn, they're shy, but they want to speak, to read, to practice English. They also like to (constantly) sing (something that is badly missing from western schools), so at one point I referred them to "simple English Wikipedia", where they can research their favorite singers with easy-to-process articles.
Empty stares.
"so instead of Wikipedia.org, you go to simple.wikipedia.org."
Still nothing.
I had to realize later that even if they knew that this free, always available encyclopedia exists, it's NOT included in their 4G subscription.
Yes, you guessed correctly: those subscriptions are sponsored by big US / Chinese corps, so all these kids had were Facebook, Instagram, WhatsApp and TikTok, everything else costs ~10$ which is days worth of meals for whole families there.
