But if I did, it'd take the form of a 'distributed intelligence agency' of devices and people that observed me, observed my interactions with the world, engaged me in conversation (and other devices and humans on my behalf), and then acted based on its perception of my need. Such actions would include filtering or augmenting my information flows (preferably, doing both). But of course, such a system would need to be controlled, and answerable, to me the user.
This is such a natural role for operating system vendors, its a wonder that Apple, Microsoft, Google, Fitbit, Amazon, Redhat, Omron, Arduino, KDE, etc, haven't cottoned onto it yet. Perhaps because building a 'society of intelligent agents' that acts in the best interests of the customer requires cooperating with 'the other'. And that is hard - both financially, and technically.
When that day comes around, my medical records, Fitbit history, readings from my home blood pressure monitor, locations from my mobile, credit card history -- all these would be brought together and 'digested'. I'd then be 'counselled' to eat healthy takeaway from WholeFoods, bypassing the PizzaHut I was walking towards. (Or not, as the case may be - I've had a stellar exercise week).
Unfortunately, commercial OS vendors and data providers are busy building or tending the walled gardens of their rent-seeking dreams. So the API hooks this 'Society of the Mind' intelligence agency requires aren't available. Until that comes to pass, we're stuck entering data into our own life.
