Sometimes our intelligence is bewitched by a metaphor. We have the sense that when we throw trash away, it actually goes “away.” There is an implicit horizon over which the trash travels as it leaves our world never to return.
We believe that the “back door” of a house is like administrative access to encrypted information by non-administrative users. As though there were some back stage from which all the strings are pulled.
Just as there is no “away,” there are no “back doors.” We need to find new words for this world we're living in.
