Except our machines are designed around the idea of isolating components and minimizing unintended side effects, while biology has no such compulsion. Imagine if an extra semicolon in one of your unused files shifted electrical distribution on storage media and that had all kinds of downstream effects on unrelated systems and those effects were critical for multiple other functions. Only increase complexity enough so the whole contraption is NOT brittle.
