I'm not going to try to think up examples.
OK. No-one apart from me has been able to provide a single example of a single use for this technology. Not a single one. And all my examples are things that I don't want. My conclusion is therefore this - any advantages of this all seeing technology are likely to be massively outweighed by the disadvantages. If Microsoft's products did this kind of thing, I would not buy them. (*)
MS apparently thinks it's iimportant enough to integrate into low levels of OSes. Much smarter minds than mine have bigger plans.
It's a pity they can't tell anyone what those plans are. I don't mean everything, just a few examples to help us (and more importantly, these 'investors') understand the direction.
BTW, I don't believe Microsoft are integrating search into the 'low levels of OS's'. It's a good idea to read a bit about operating systems to understand how and where a service like this is integrated. For example, I don't believe the NT kernel (which is now used by all Windows OS's) will have any dependency on a search technology.
If you don't want MS to build a foundation for the future, but instead want them to think short term, that's your business.
I don't want anything from Microsoft. I am completely neutral. Except that I may be a Microsoft shareholder, so Microsoft may be paying some of my pension, and therefore I want some reassurance that this will all one day make some money.
BTW, my 'creepy examples' above do provide some reasons for Microsoft to keep Bing. Advertisers and governments would love the opportunities this constant monitoring of the public offers (*). It's bad for us as users, but may be very profitable.
Any positive examples are still welcome and might yet change my mind!
(*) Assuming this constant monitoring is really what Microsoft have planned - I didn't see such an announcement myself.
