I think an article named "The ethics of..." is meant to "dabble around ethics" rather than explaining the technology. There must be other articles/papers about that.
Yes, but because it's such a weird/new piece of technology, I think an explanation of how well it actually works would be a good compliment to the article, there's no point in talking about ethics if it doesn't actually work.
How well it _currently_ works is irrelevant from ethics point of view. Ethics are only concerned with how it could potentially be used. That's important to think about, so that the researchers know what direction to go and how to conduct their research so that it wont cause problems in the future.
