> - Anything written down [..] > - Anything I say to someone [..] In my hierarchy these two points are swapped. At least I think there is a real chance to keep written material secret as long as you are not a target of a state level adversary. I can write in a room where I am sure there are no cameras watching and I can put my copy in a safe where I would know if it was compromised. On the other hand I can almost never be sure not be audio recorded - be it deliberately or accidentally by any of the microphones that are almost everywhere nowadays.
