The new samsung phones will automatically summarize your phone conversations "for" you. I could go back and say "what time did Tyler say to be at the BBQ again?" and actually see a bullet point of it from a phone conversation we had, and so can everyone else with access to that data.

The modern day accuracy of text to speech alone, that hundreds of millions have been training using Siri/Alexa etc is making unprecedented levels of surveilance possible.
