I am concerned that, with the vast information already stored via computers, accessible at the touch of a finger, humanity may lose its capacity for functional memory.
There is an old literary joke - that was stated in a very humorous poem, once published in The New Yorker : "Ha hah! the book of my enemy has been remaindered!" Now, I guess the exultant cry might well be, "ha ha! the text of my enemy has been corrupted!"
The exigencies of Temporal Displacement require that I regularly subject my own memory to "data scrubbing".
