Here in Brazil, this system exists, but without a blockchain, and it works very well. It tracks vaccinations, surgeries, when you went to a hospital or a basic health unit (it's like a mini hospital for check-ups, vaccination and less severe stuff), etc.
I went to a doctor recently (that I never went before) and he started asking things like "so you broke your arm on 2003? Interesting".
So I would say that blockchain might not help in that area either haha.
What dies "better" mean? If everything is stored on a single server owned by this one company in Mountain View or so, is it better then?
Nothing and no one is ever infallible. What I say is that the web as we know it is broken in that it has become a walled garden controllled by a few companies. And, yes, a lot of web3 doesn't appear to change that, it's just old wine in new bottles. We needed to discuss alternatives to different use case (payment and currency systems, how we monetize apps and other products, data hosting and sharing,. ..). Energy efficiency and affordability are important issues, but I want to have choice and don't want to become dependent on 5 or so companies in whatever I do. If that means that I have to pay,, I'd be fine with that.
Yes, that's one solution for a specific use case (-:
