I am so so torn on this. It's hard to put a price tag on a human life. I imagine some people would even say that a life is literally priceless.

Given infinite resources, I would agree: if a life can be saved at any cost, then save it. But we don't have infinite resources. If the quality of other patient care was reduced because of attempts to keep this girl alive (if "alive" is indeed the right term), is that trade off worth it? I'm not sure. I mean, given the extraordinary results they've gotten so far, it's possible that, given more time (perhaps on the scale of decades), she'd get to a point where she'd be able to communicate more richly with people around her. Is it worth spending tens (hundreds?) of millions of (public!) dollars to get her there, especially if other people with better prognoses are getting worse care because of it? I'm not sure I can say yes to that. But I've also never been in a position where a loved one was in dire straits to the point where throwing heaps of money at the problem would help, so I don't know how that feels.
