Last week science fiction writer Ted Chiang came to Riverside to talk about the possible cognitive effects of video lifelogging. He also explores these issues in his 2013 story The Truth of Fact, the Truth of Feeling. It was an interesting talk! Chiang focused, as he also does in the story, on the transformative effects video lifelogging might have on our memories, including the possible decline of our ability to remember life events unaided if we can instead just easily call up results from a lifelog.
Lifelogging is a movement aimed at recording and monitoring the details of your everyday life. Video lifelogging, which is just starting to become feasible, involves video-recording every moment of your waking day.
Good search technology will be crucial. Imagine subvocalizing "the name of that book Emmeline recommended at dinner last week" or "that time Taimur cracked a raw egg on his head", then having the relevant audiovisual results show up on your palm or your Google glass. The eventual effects on our minds, Chiang suggests, would be comparable to the transformative effects of literacy. In his talk, Chiang emphasized the decline of unaided memory and the ability to hold ourselves to higher standards of truthfulness about past deeds (what did you really say in that argument last week?).
Just as early Chinese calligraphers could not have predicted quantitative textual analysis or the internet, I think we can assume that if video lifelogging is integrated deeply into our daily lives, it will change us in ways we can't fully anticipate. I'd like to suggest two possible effects that Chiang didn't mention.
First: It is much easier to record audio and video than other sensory modalities. The recording and recreation of taste, smell, touch, and somatic sensation are much more speculative and remote. Most people already tend to privilege sight and hearing, but lifelogging could amplify that dominance -- perhaps so much that the other senses almost seem like a forgettable, buzzing distraction. Your memories of sex, for example, might focus much more on the audiovisual parts of the experience, if those are what you can easily revisit and recall (esp. with decreases in unaided memory, as Chiang suggests would be likely) -- and that in turn might lead you to focus more on those senses than on other senses in your future encounters, which in turn might substantially alter the cultural structures and expectations around sex. Similarly, perhaps, for the pleasures of eating.
Second: Chiang had explicitly set aside privacy issues, and I will also do so (maybe Cory Doctorow will address these when he comes next fall), but intentional sharing raises interesting possibilities, especially if it's possible in real-time. Suppose we can't all afford to go to the concert -- but if we pool our funds, you can go, and we can all watch your lifelog in real-time (perhaps in immersive virtual reality), which will then be saved in our lifelogs. If our cognition and culture have shifted more toward the audiovisual, then it might seem closer to actually being there than it would seem to people now, and if our autobiographical memories have become dominated by lifelog results, then later it might feel more like a real memory of having been there than an analogous experience would seem to people now. Pushed to the extreme, an emphasis on shared real-time and remembered experiences might begin to blur the boundaries of the experienced self, including reducing how much we care about whether it was our own bodies that did something or someone else's.
Just for starters.
