I thought that about Pike, too. The difference may be that Ariam was severely injured in a shuttle accident and Pike was a victim of radiation that did irreparable damage. The real question is, how common was Ariam's treatment after her accident? Accidents happen, as they say. Are there others like her? It may have been experimental from the beginning. Further, there would be ethical issues. Did they get her permission to do what they did? Is someone automatically given the type of life they gave her if needed, or do they get to refuse it? Another question would be why the treatment wouldn't make the person look a bit more cosmetically human (or whatever species the person was). That is, more like they once were.
