Okay as the arguements seem to be getting repeated here, and they aren't answering my problem with the setup I'll try a different tact.
Let's say I've just been hit in the head by a pigeon. I think to myself I don't want that to happen again, I know I'll make something to protect myself. Now I could make a gun to do this. Guns don't have brains however. Oh no you say, now what? Well, I could actually AIM it at the pigeon, instead of letting the gun roam free in the hope that despite it not having a brain it might do something useful.
Now many of you seem to believe that my actual course of action shouldn't be along these lines. Instead I should make a mouse. Now the mouse is completely useless against pigeons, and I have no way to aim it. However I can let it roam free, and it will attack small pieces of cheese which may possibly at some point in the future have decided to become dangerous and attack me.
