It's already ephemeral and decays by itself. Honestly as a polyglot, only a Go project can run without being touched for 5 years. The rest of them get vulnerabilities discovered in the packages, which requires you to upgrade, which changes the feature set and takes re-work. Also design ages, UX paradigms change over time, look at the "web 2.0" look today and the "web 1.0" of before. Skeuomorphic design aged as fast as Garage and Jungle music did in the 90s. This will be the same with flat design and neuomorphic design in 5-10 years, if there is even an UI then. All in all, software does decay and we lose data every day. Try go through your oldest bookmarks, many sites will be gone. Or run software that used to run on windows 98 or DOS or amiga or classic mac, you need to jump through hoops, the UX will be terrible, that's aging. Software doesn't need artificial aging, it erodes well all by itself. Even fast moving code in a startup changes so much from week to week, your merges can be difficult. That's like a river bed redefining itself during a rain storm. As humans go through time, so does software as an extension.
