I agree it’s something to not take lightly. I accept the use of technology to return the human body to a normative state (i.e skin grafts for burn victims, regenerating organ tissue). But I’m leery of attempts to “evolve” via machinery. It may further take us away from the gravitational center of being close to our natures/Nature—a distancing we’re already suffering from greatly. Though admittedly I haven’t studied the proposed “machine merging” in depth.
