While the digital does not degrade at a level anywhere near the analog, it can grow old. In the words of Project Gutenberg founder Michael Hart " Alice in Wonderland, the Bible, Shakespeare, the Koran and many others will be with us as long as civilization ... an operating system, a program, a markup system ... will not.". Code is constantly changing and it's hard to keep everything up to date. Many of the new operating systems do not offer much backward compatibility, thus the new waves of technology are constantly making yesterday's gadgets extinct. The use of old technology in these stories, such as the type writers in Max Headroom, reveals a societal nostalgia. Jonathan Wang explores the phenomenon in depth in his essay "The Future is Past".
