Ambient Intelligence where is it ..?

Similar to the question two weeks ago about the whereabouts of smart dust, here now the opposite (more on that below): Where has all the Ambient Intelligence gone ..?
And I don’t mean Smart Dust of some kind that the Release of Colorado has dwarfed some niche markets elsewhere (it hasn’t, I gather?), but the dust of nanobots that could be sprayed around just anywhere and drift in the wind, as hard to detect, spread-out snooping devices. Either for the good, puffing around IoT-sensor en masse, or for the bad, (video)eavesdropping invisibly, undetected.

Ambient Intelligence then would be opposite as it would deliver seamless Intelligence of the Watson^3 kind, AGI or ASI, to just where you would find yourself in need (as detected by that intelligence before you realized it) e.g., in the form of hyper-personalized ads. When you walk by a store front window. So you’d be enticed to buy more, more, more. Yes it’s sad but that’s the most clear example that everyone apparently needs; anything more complex is too much asked of your dumbed-down, numbed, nerve center that exist for the pleasure of your iSomething these days.

Before I turn sour: The idea gained traction some five years ago. Where is it; in hiding? In some black programs by DARPA, Fubbuck, Big G et al. so much out of sight we have no clue of the massive budgets being spent to gain control over us all ..? Just a shout-out for your pointers.
