I wonder how hard would it be to just write off the Internet and go full offline. Setup a local LLAMa instance, download Wikipedia, torrent every movie and tv show from the last 40 years, clone all the github projects. It might sound crazy, but I remember people archiving entire discographies of their favorite artists on a single DVD. How much can you fit on single, modern HDD?
