Zero trust policy is slowly making its way into every day life. Maybe for the best? Trust the people you can talk to, feel, see.
Within humans I don't think, for every interaction with the any form of output, "Well, did the human do it themselves or merely pay some other human to make all the decisions?"
Walking into someone's home I'm not thinking "Wow, beautiful decorating and design aesthetic. I'll have to be sure to find out if it was done by an interior design contractor with a free hand in making all decisions so I know how to calibrate my level of enjoyment of it"
