The Reversal Test is a good thing to think about when examining the possibility of Status Quo Bias: If you had the option to make your memory more unreliable, or to give up what videos, photographs, and other recordings of your life that you currently have; would you take it?

If not, what makes you think that the current spot on the continuum from "accurate/prosthetic memories" to "inaccurate/solely internal memories" is the best spot?

Maybe not surrogate, but the ability to back up memory and maybe index it would be almost equally transformational and wouldn't involve having perfect recall of every time you screwed up. I know that wouldn't solve the issues raised in "The Entire History of You", but I'm not entirely sold "forgetting it happened" is a better solution to that episode anyway.
