Thanks to the sacrifice of these clueless users (or at least a good part of them are) the era of offline assistants is near looking at what Google has shown recently.
I think I'm being clueless, but I can't figure out what this sentence means. Is there a typo in it?
I think that this is an important point. Obviously there's more computing power available in Apple/Google/whoever's data centres than on my device, and I'm sure that is, or at least was, a concern; but I also don't believe that they are indifferent to the utility of sitting on such a huge volume of user-submitted, real-world data.
