Software can be classified as alive. Not using the Wikipedia definition of alive, because that requires biological processes, but philosophically seen software is kind of like a living organism. There are constant changes as the software evolves, adapts to environmental changes and grows new features.
But what if it stops changing? Can software die? What about software that is
“done”? One of the most used tools on UNIX machines is
echo. The current GNU
implementation which is arguably the most widely used one (assuming most OS X
users rarely use it) is at the time of writing about 270 lines of code,
and is already considered bloated by some.
But despite it being quite large and filled with features, especially compared
to its BSD counterparts, there have been no meaningful changes in several
echo dead, or is it just finished? As it stands right now,
there probably are features that could be added, but none that make
sense. And with just 270 lines of code chances are that
echo might actually
be entirely bug-free and always working as intended.
But do not go into paradox-induced freeze just yet, for I have a solution to this dilemma. Software can be considered alive, but in a different way. In the first paragraph I used the term “evolve”. If we think of a piece of software as a species that undergoes evolution and following that consider a single version a member of that species, things start to make sense. A program can die, it can crash or exit gracefully after having lived for its expected lifetime. A piece of software can stop evolution, end even though biological evolution cannot, it could effectively slow down to a halt if the perfect form is reached, which is of course impossible in practice. And if no one runs a piece of software anymore, it can go extinct.
So the answer is yes, software can die, but it does not happen when change stops occurring. Because of the drastically more limited scope of software compared to biological life, software has a real chance of achieving perfection, a state in which no changes are required or desired.
