I wish that I had done this in my previous relationship. We were young, and we talked a lot, but I didn't realize what was really important to her (travelling, saving money). So when we'd talk about goals, I'd never realize how much things meant to her. A contract may have helped us define our goals, and what we wanted, and make things a little easier for dense ol' me.
It seems that you need more, and more complete information to do deep learning on records, but it also seems this is a first small step into centralizing and using health records for public health.
It would be interesting if people are already starting to gather as much data about themselves that will relevant in few years when similar tech is widely available. For example, taking a photo of each of your meals might prove to be good investment of your time down the line.
