My experience has been quite the opposite in terms of convenience and relevance: I commute by car and train (for some parts of the same journey) and google Now, google Maps (etc) have been totally useless there: telling me about traffice jams when I'm in the train, not telling me about train delays, etc... it now somehow thinks my home is at the train station, it tells me the last bus home is leaving soon when I've been home for hours, also Google Now's insistence on bombarding the leftmost pane on my phone with the most click-bait articles ever, often about things I had a passing interest in months ago, is just laughable. I would be glad to give Google some of my very precious privacy, implementing some countermeasures like multiple and burner identities as needed, if I thought they had any chance of actually providing real value. So far they have failed miserably, I am not sure the economics of providing a really useful service there for free just with marketing information as source of income work now, or for a very long time. You'd need strong AI to actually help my day to day life, with solid non obvious guessing based on many very local and specific factors. I guess as long as people kind of believe that this future is coming, they may tolerate the invasion and forget about the promises.
