All software is subject to shifting environments over time that will eventually render it obsolete. How fast this happens really depends on the ecosystem—it's a function of the abstraction level and context in which it runs. C or Go code that compiles to a standalone binary will be less susceptible to this, higher level Ruby or Node code that depends on a lot of peer libraries moving in lockstep will be more susceptible. Newer languages that have some notion of backwards compatibility baked into their charter like Elixir or Rust are somewhere in between.
