Computers Could Replace Judges

Based on the excuses by the two Federal Courts who have refused to do anything to save Terri Schiavo - (in my opinion) a narrow definition of the law - we really don't need human beings to serve as judges anymore, in my opinion. Afterall, we can just treat it as a computer function:

Ruling = (Arguments and evidence by plaintiff + arguments and evidence by defense + relevant laws + previous relevant rulings)

Human beings are supposed be able to consider decision from a human factor, not JUST use the (my opinion) cold and unfeeling response a computer might give. In my opinion, they may as well have just used a computer to decide instead of human judges.
