The possibilities for this technology are endless and so are the ethical dilemmas. I'm not really sure where to start, but neither are the researchers.
Mostly, the technology has been proposed to help detach people from the strong emotional reactions that accompany traumatic memories and are usually associated with PTSD (post-traumatic stress disorder). In theory, PTSD will be reduced, but I think that the potential for this technology to be abused is very strong.
Hopefully this will have strong restrictions to the use of it and will only be used as a last resort.
