Once humans have obtained absolute power and control over the genetic code of DNA, any creature imaginable could be drawn as a blueprint and grown. In other words flying monsters the size of buildings could be grown. These creatures could be used to fly people around the world; they would consume food, rather than a combustible fuel. These genetically engineered creatures may not require mechanical motion and precise shape. Currently, transportation vehicles are rigid and heavy. Thus they will be made of cells and move in a fluid and flexible motion. These creatures will instead resemble dinosaurs, sci-fi characters or any other creature born on Earth. However, reaching this state of genetic control would almost certainly coincide with the ability to grow new intelligent species.
