Depends on what you mean by "simple". In my head, specifically with software, simple is defined as "does less", which is definitely somewhat easier to make, than a complex program that "does more".

That is an understatement! And not only that, "simple" is relative. The common saying that gets push back is "Do the simplest thing possible." People always seem to ignore the "possible" part of that phrase. Forgive me for being a little cute here, but a complex solution is simpler than a really complex solution.
