Google: One Laptop per Child ;)

replace education in places without electricity with survival in case of civilization end.

Or a USB stick filled with knowledge and entertainment for a budget price.

A USB stick with all public domain content would be amazing. New one each year; loads of stuff on it!

You'd need a full size SSD (hundreds of terabytes), not a USB stick (2 terabytes today).

I actually really like this idea.

Choose some reasonably good llm model + corpus of data to enhance the generation (e.g. wikipedia).

Package it in a long-lasting battery, rough device. Think of a tablet/laptop you would take deep into the desert for a multi-week trip.

A solar panel would be capable of charging a laptop. Perhaps one of those could be ruggedized along with the package.

.. and to maximize profit, make it live-updateable and subscription-based. And don't forget periodic online license checks which are mandatory for app to run.

You forgot the targetted ads, with the subscription tier to reduce it from 100 ads per page to just 10.

You also want to make sure you know exactly what your users are doing so you can offer the best experience.

Include a key logger and a daemon to grab full screenshots every few seconds.

Bring back some old school methods with a modern twist too - upload all your contacts.

Instead of just emailing everyone inviting them to join and telling them which kind friend reccomended they join - use the birthday and home address information and send them real tangible marketing material for their birthday (+ on Anniversaries, Christmas, Easter and on any day ending with a "y").

That's may need over million TB to collect all data, actually is there anyway to host they data without doing cloud or Hardiver things in the world?
