Lets say you live in a world where the world government has decided people are getting too addicted to the internet and ordered the internet to be shut down for 5 years. The 100 GB of storage is all you have (excluding essential system files for your Operating System). You have 24 hours before the internet is getting shut down. What do you download?
For myself? A midi-file library for music (1gb is easily tens of thousands of songs), some audio porn (video takes too much space), a whole bunch of E-Books (tabletop rpg, science, literature etc.), compilers for C, a bunch of core python packages etc.
Meanwhile I’d also head over to my university to warn staff of the impending doom such that they can spread the word to other institutions and start rescuing as much data as possible to non-digital formats.
