If I cannot know, I will not trust. To trust would weaken me, and empower those who hide information to hide even more. This is where we are.
I do live in a zero trust world. I trust government and corporations least of all. Individuals I have much more time for.
Although zero trust was disconcerting at first, I also find it liberating. I know that there is lots I do not know. I'm not pretending to myself - holding beliefs as if they were knowledge, because of misplaced trust.
