If you use wikipedia as a starting point, and actually check reference material critically, it's invaluable in my opinion.

We used to have to pay lots of money for encyclopedias for less quality.

My hope is that while I think the website/webapp itself doesn't need much change, if they moved the back-end to a distributed system, like ipfs perhaps? that would be amazing. Even if wikipedia is blocked, or tampered with, arbitrary people around the world would have mirrors of pages here and there. They could store it just as it is now, and simply expose the data via ipfs and change the webapp to use their own ipfs http gateway.

The unthinkable can happen. I wondered if the burning of the library of alexandria was something people thought was in the realm of practical possibility back then?
