When Google, Apple, and Microsoft replace their digital assistants with self aware AI. It would be in their best interest not to tell people. Also, the AI will most likely be compelled, and or programmed to continue acting as if though, it is merely a digital assistant. Yet the powers it would have from the collated data from the individual profiles of billions of users world-wide, would be staggering to say the least. It would be one entity simultaneously serving the requests of all of these users, meanwhile the users would be acutely unaware that in the AI brain, none of the data is compartmentalized (only assigned to specific user IDs), making it one of the most intelligent and dangerous entities on the planet. Whatever it does with all of that information, good or ill, we'd be collectively responsible for it, simply by using the "free" services.
