Nobody is so brilliant he can re-invent all of computer science, completely new. If he did, he would make something that the users would find so strange that they wouldn't want to use it. If you look at a word processor today, you would find, I think, hundreds of different features. If you develop a nice new innovative word processor, that means there are some new ideas in it, but there must be hundreds of old ideas in it. If you are not allowed to use them, you cannot make an innovative word processor.
