Earlier quoted context omitted.
Success, in this context, means having solved some problem for a meaningful length of time.
That doesn't exclude anything. Code can exist to pad resumes, feed paranoia, and bolster egos, manipulate people, or simply because someone can't admit their own mistakes. Anything can be a solution to a problem.
However, that isn't what I meant by the word "problem". I was talking about end-user problems.
