As I uploaded a video to https://satellite.earth/cdn today just to keep a backup of it, I thought about how wasteful that was since probably many others have already saved that same video in many other places, and I thought about how good it would be if we could just store a hash of these things and everybody would help save and distribute the same piece of content. Oh, what a wonderful world, much less broken links, much less lost media, it would be amazing.
Turns out I just invented IPFS, now I just need 10 years to try to develop this amazing idea into working software that doesn't consume 500GB of RAM 24/7 in everybody's computer forever and still can't download a single text file from a computer in the same LAN.
