Of course any system will require maintenance. The question is more about the significance and frequency of the maintenance required. You can take a Ruby on Rails app from 2005, and it will mostly look the same as a 2023 Rails app. You'll need to update some gems, use the newer routing DSL, and update the environment configs. But that's pretty much it, after nearly 2 decades. Contrast that to a React app written 5 years ago, where you'd pretty much need to completely rewrite everything (class components => functional, use hooks instead of callback methods, etc.)
