I like how you redefine PRIVATE from "something I can see" to "something I can see and Google machines can add to and edit at whim, and Google employees hired by strangers for profit, an unknown number in unknown places, with no individual accountability, can potentially access" and then use your new definition of PRIVATE-which-isn't to bludgeon other people as luddites.
This whole thing is the culmination of years of singularity "the computer will expand the mind" rhetoric.
This isn't your mind being expanded, this isn't you thinking new thoughts.
This is what everyone has been trying to build for years. We are here. And all of a sudden it's creepy?
Kurzweil VoicePad and Dragon Naturally Speaking tried to build Voice Recognition on-device for years and it was a bright and techno future. Then Google Now, Siri, Cortana and Alexa got people to send speech samples over the internet to a foreign, perpetual-record, datacenter. The voice recognition part is better, but now it's creepy.
Email has been turned into a useful automatically actionable system. My family forwards their itineraries and I don't have do anything else, it's automatically calendared. That's probably the only reason I pick them up from the airport frankly.
Why doesn't Google forward their itinerary to Uber and have someone else pick them up at the airport, so you don't have to be involved in your life at all?
