Two days ago, I'd have said the same. Yesterday, big box went down, and because it was so stable, it was a joint less oiled and the spare chickened out at the wrong time and apparently even managed to mess up the database timeline. Today was the post-mortem, and it was rough.
I'm just saying, simple is nice and fast when it works, until it doesn't. I'm not saying to make everything complex, just to remember life is a survivor's game.
