Philip K Dick wrote "Do Androids Dream of Electric Sheep?" instead of the obvious "Do Clones Dream of Cloned Sheep?". This proves that his mind was suffering, probably was schizophrenic. Or maybe he was working for the elite and was asked to not write something that can expose them. Nobody can be so demented to write a story about clones and call them androids instead of simply clones. I do appreciate his effort, but the fact that he was demented is very annoying. Being mentally sane would have saved some lives, you know. If you are going to write sci-fi stories, make sure you are not schizophrenic, so you can help other people.
