This is sad, because I believe tens of millions of lives could be saved by giving all healthcare data to Google to do with as it pleases.
Sure, privacy would probably be impacted, but in my opinion, life and death is more important than privacy.
We're talking far more lives than terrorism here, and we were happy to lose a lot more privacy for that. Probably more lives than guns, car accidents, etc. too.
When we've saved those millions of lives, we can work on ways to get the benefits of both privacy and still saving those lives.
