I guess you need to compartmentalise into different kinds of 'trust'. The not 'trusting' you do with a computer is different from the trusting you do with fellow humans in daily life. They just happen to use the same word in English.
I trust the computer far more than the fellow humans. The computer will generally give a predictable output for a given input. "fellow humans in daily life" .... not so much.
Its terrifying; sometimes when I am crossing the street people accelerate, sometimes they slow down, sometimes they stop at red lights, sometimes they drive through them.
