Here is a video on IBM Watson Health Centralized Thinking Hub on a Cloud.
The hub collates the data of billions of people and ‘converts that data into knowledge’. So what it does, is that it deciphers an ailment and makes suggestions to a patient according to his/ her other conditions.
The hub is touted as a breakthrough advancement in creating medical communities that thrives on interactive ecosystem and security identification
Having said that,
Every technology has its lapses and a whole data can perhaps only predict generic list of recommendations that may or may not be pliable to one or the other. Also there would be a growing concern of personal data security breaches and contrary medical findings!
But here is a thumbs up to a step forward in medical advancement.
