I loved Black Mirror (so happy it's getting a 2nd season!), but most of the issues in that episode are due to the main character's shitty life. The neuroticism about his interview, the issues with his relationship, his wife throwing his poorly chosen words back at him, all those would be possible with regular memory. The removal of the grain and "play it back for us!" reaction to his bad interview seem like unusual cases, although I think only time will be able to tell how social norms will form with the second part.
