Clearly this is what we want to hear, but do you know something concrete? Feel free to add teaser dates, vague references to AI, or the word 'space' in your response.
Watch sergey's interview with tim o'reilly on youtube from last week, he mentions that something out of x lab will be coming out by the end of this year. Also, the fact that he's not actively working on google+ and their cutting of previously ambitious projects like energy, google health, etc and the new york times article mentions stanford and nyu, welll known neural network researchers (andrew ng and yann lecunn) means it's probably ai related, probably neural networks applied to computer vision. Space, i probably don't think so.
Of course this is all speculation, i don't have any inside info.
A centralized medical records system is more political, social and procedural than any sort of technological revolution. The technology to create one has been around for decades.
Funnily enough Microsoft was pushing down the centralised health route a long time back, but gave up because everyone was worried about them holding centralised information. This was back in the days were passport was trying to be rolled out as a single signon solution.
The more things change, the more they stay the same...
