Why are computers better than humans?

Computers are better than humans in some aspects. They are never incorrect. They behave like a machine, so they don't have emotions to affect the output and they always follow the same path unless they are directed not to.

On the other hand, a computer needs to be told how to interpret something. They require detailed structured information to gives us the results we want, and it can't make decisions like humans can to correct as they go along. Ex. when we are told to go to a door and open the handle, we can judge how far we need to walk, we judge which way to turn the handle, we judge what to do if there are obstacles or the door is locked. A robot cannot make these corrections and needs to be programmed step by step to open a handle. It also can't interpret information that is outside of their programming (ex. you could read the follow 'A' and you would know its a letter A. You could also read 'a' and know its a letter A. You could read it written in cursive, or by a child, or by your own hand, or see the letter A in a cloud, or in a tree, or in a reflection.) Furthermore, as computers are made by humans, they contain humans' mistakes.
