I highly suggest you read the above quoted book by the American Bar Association on drafting patents. Emotionally repeating your own personal definition of the word idea helps no one. When we use the word idea in the context of invention, we are talking about the idea of an implementation. For example, the idea behind a steam engine, it might be at its most general: driving a piston with steam. If this idea did not have prior art, you most certainly could patent it as the idea embodies a technique. Unfortunately, I don't have a good go-to source explaining what computer science is, but I assure you that computer science does not involve writing science fiction novels.
