In Should We Let Computers Get Under Our Skin, Jim Moor claimed that since ethics is determined by one's nature, a decision to change one's nature cannot be settled by ethics. But I contend that we can rationally choose to become cyborgs, and we should be open to radical change. If we have a nature that entails self-transformation, then ethics should cover such situations, and so I argue that humans are transformative beings. As demonstrated by Richard Volkman in Playing God, part of flourishing for a human is overcoming one's limitations. But one's limitations are part of one's nature. And so changing one's nature is a part of what it is to flourish for a human. Since we use the development of technology to overcome our limitations, progress is necessary for flourishing. Because progress happens through unpredictable processes, no one unchanging plan will prepare us for the future. Therefore, dynamism is an important part of progress. And since progress is a part of flourishing, dynamism is therefore constitutive of flourishing for humans.
