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.

Again

Just because something has been done many times before, doesn't mean it shouldn't be done again. Yes, the awareness is helpful to some extent. But you will always bring something new.

I'm thinking of my project of writing an accelerator optics code in Calc. What can I do differently? Can I document it better than MAD? Can I make it easier to use?
This area has such a heavy history. Too many codes already. Yes, I'm writing another one. But maybe I can bring something good to the process, and even the result?
