You're right. The preference would be that each person has access to a single part of the black box and no access to anyone or any other part of the whole shebang. Either that or the old way of dealing with people involved in things that have to remain secret. Of course, you behead enough OS devs and soon there won't be any. As far as my daily life, no not really. I just live a life where I grant very few people a view into the things I consider private, and ensure that every two or three people know contradictory things without knowing the parts that put them together. It leads to a robust but distant social web.
