works too well

There are some things that work just too well.
Like google search, whatever you put in, you get something back, as if you meant it.

I was going to try to run a program I am writing, and realized that I hadn't written everything that I need to yet. I was thinking, could the code somehow be smart enough to guess what I wanted to do, and then just run? Why do I have to take the time to put all these explicit instructions in there? Of course the reason is that it is based on rules that I understand, so I have a certain measure of control in the situation. If the code could decide itself what it thought that I wanted to do, then its no longer a situation based on rules that I can understand to whatever degree I want.

I'm not saying I think Google should crash on badly phrased searches, but having hidden rules with a goal of never failing and always trying to guess what you want takes the control away from the people using the code and puts it into those writing it.
