I don’t understand why some areas would warrant the response of “sometimes it works and sometimes it doesn’t”. What if we left other areas examined? “Let’s not bother to research sorting algorithms further. Some people write a sort and it goes fast, and some people write one and it goes slow, and that’s just the way it is”.

It would be an awful shame if we were not as a species able to make effective use of all of us because we preferred to leave this to chance.
