What? In the sense that better to have that problem than just already dead because ECMO doesn't exist, you mean?
Otherwise I can't think of any way it's at all nice, and that applies to any dilemma - you can always say 'oh well nice to have the option, better than only the bad lemma'!
I mean that countless people going forward will be saved by this. Some people will become ICU bound walking corpses. It’s an incredible technology that will have profound benefits for humanity.
