I did a web search asking if Fitbit can tell if one is a wanker, and the consensus seems to be “Yes.”
I wonder what Google will do with all that accelerometer data.
What does Siri say?
Google will probably helpfully inform your insurance company that you have high blood pressure or some other condition. Not in way that breaks HIPPA but in some other way that it can be inferred through the magic of data science and de-anonymization.
