I feel like Google have the power behind them to try to at the very least data mine the free text data for information. Possibly they even have enough sway to convince doctors and other individuals towards a form that is far less random, or at least to provide a platform to share information between patients. Note that NLP seems to have come a long way in five years, who knows where we'll be in a decade or more. In terms of incorrect records, I'm not sure this would be a major problem over a large dataset. Making this up, but I imagine the range of errors is fairly random across all fields and with enough data you can always identify an approach that appears to save a life more than some other approach, even if the diagnosis is incorrect. Although I totally agree with you that this is going to be an enormous challenge for Google, I feel like it would be underestimating them to assume this has very little hope of succeeding.
