Great sci-fi begins with an idea. Unfortunately, as people will tell you, all the good ideas were taken long ago. But that's only true if you believe ideas are indivisible, like, "A guy goes on a journey and experiences personal change" covers everything from Moby Dick to me visiting the bathroom. In fact, ideas are totally divisible. There's no idea that you can't make new by filtering it through your brain. Such as, making of a robot. This is the most hardworking idea. But, it's need to be a peaceful idea. Science fiction is the most incridable topic which is always trending to everybody. This is the future of our world.
