Here is one truth about aging that we don’t talk about often: we are much more ashamed of signs of mental decline than we are of the physical decay of our bodies. We don’t like our aging spots or wrinkles, but they don’t make us feel inadequate in the same way that forgetting a name or an appointment does. Why is it that none of the physical infirmities of old age shame me? I am not ashamed of my grey hair or the fact that I can no longer hike six miles. I don’t like the brown spots on my hands, but I am not really ashamed of them. But the mind is different. When I forget a name or a common word and have to fish for it, I can exclaim, “Senior Moment!” and laugh – but I really do not think it is funny. I think it is a profound loss. And that is not good for the serenity I have been seeking.
Last week my husband came in after a morning errand to tell me that I had forgotten to put the gas cap on and close the little door after I filled up the car the day before. I had also neglected to notice the message on my dashboard that would have reminded me to go do it. I felt awful. I occasionally leave a burner on or leave a light burning when I go to bed. And, of course, I fish around for names and sometimes ordinary words. I have always been somewhat absent-minded (as was my mother before me), but it seems to be getting a little worse and more mortifying.
The aging of my physical body does not please me, but it does not mortify me. I stopped dyeing my hair a dozen years ago; I wear little makeup and have not explored plastic surgery, although I did have my upper eyelids lifted when I started having trouble seeing beyond their droop. Why the difference?
We clearly don’t identify our selves with our aging bodies. There is Freud’s recollection of catching an unexpected glimpse of himself in a mirror:
Jumping up with the intention of putting him right, I at once realized to my dismay that the intruder was nothing but my own reflection in the looking-glass of the open door. I can still recollect that I thoroughly disliked his appearance. (from “The Uncanny”)
Similarly, Jonathan Swift, upon being led across a room in his dotage, caught sight of himself in a mirror and cried out “O poor old man.” And so cry we all. And yet, loss of the mind – even in bits and pieces – is worse. Many of us fear it more than physical death. Is the reason we are afraid to die not the loss of the body, but the fact that the body will take our consciousness, our sense of identity with it?
And is our source of identity the reason that AI scares us so much? Artificial hips or implanted lenses don’t scare us. We are grateful for them. We don’t mind using motorized scooters if we can’t walk or using hearing aids when we can’t hear. No one is afraid of wearing glasses. But do we want technology to replace our brain? If we could implant something in our brain to “help” us remember names, would we want to do it?
One of the best sources of how AI was developed is a small book, The Maniac, by Benjamin Labatut. He tells the story of Johnny von Neumann, which leads into the story of Demis Hassabis, a developer of AI and the founder of DeepMind. I strongly recommend this book – a lucid read on a difficult subject. Hassabis finds no problem with developing a machine that can think better than we can, and he does. One of the proofs is that his AI can beat chess masters, and also the masters of Go, a game developed in China over 2,500 years ago, with a system of grand masters known for their wisdom as well as their skill. In 2016, his AI program took on the master Lee Sedol in Korea for the best of five games with the understanding that all five games would be played regardless of outcome. AI handily won the first three. Sedol was demoralized, but persevered and somehow beat AI in the fourth game. The crowd exploded:
Outside the hotel, Lee’s fans were running in the streets of Seoul, chanting and celebrating their hero’s victory. Even the team at DeepMind, who had lost, rather embarrassingly, were amazed at Lee’s stunning ability to create something out of nothing. How could a man, however smart, defeat a computer like AlphaGo, able to calculate over two hundred million positions a second. Surely it was a feat that would go down in history… something that all mankind could truly celebrate. (The Maniac)
Why were they so happy? Sedol had already lost the tournament. They were happy because AI threatens our very identity, our purpose, our souls. Needless to say, Hassabis was not happy. DeepMind fixed AlphaGo and Lee Sedol retired a short time later calling AI “an entity that cannot be defeated.” He said his “entire world had collapsed.” Why would anyone play Go again? (I’ll come back to that.)
AI will not get old and forget names and leave the gas cap off. It will get more and more perfect as my brain probably gets more and more unreliable. But it is my brain. It has brought me this far with its own memories and capacities. If it were fixed, I would not be me.
In his Essay Concerning Human Understanding (1690), Locke had taken up the subject of personal identity, connecting personhood to consciousness and memory:
For since consciousness always accompanies thinking, and it is that that makes everyone to be what he calls self, and thereby distinguishes himself from all other thinking things: in this alone consists personal identity, i.e. the sameness of a rational being. And as far as this consciousness can be extended backwards to any past action or thought, so far reaches the identity of that person. (II: xxvii: 9)
Linking consciousness and memory to identity is problematic in relation to old age, when changes in cognitive abilities may challenge our assurance of continuous identity. I will have to accept that. But that same consciousness is my personal identity. To lose that identity to a machine would be a living death.
I do what I can for my memory. I push myself to read difficult books, I do puzzles, I enroll in a French class. I create appointment reminders. I check the stove before I go to bed. But it is a little silly to accept that the body is changing while refusing to believe that our gray matter is affected too. And perhaps it is even sillier to think we can patch up our minds with computer chips and not lose our selves in the process. In the end I am less afraid of my aging mind than I am of AI.
And I continue to enjoy doing the things that AI could do for me. I play the piano when I could stream Glen Gould playing Bach, I knit hats that computerized mills can make much more quickly and error-free. I do not use AI to write my blog. There is a sense of satisfaction and accomplishment in doing such things. But I had these habits before the advent of AI; I despair for the children.
In Capek’s play R.U.R. (Rossum’s Universal Robots and where the term robot originated), about the takeover of robots as they first serve mankind and then get rid of them, one of the humans cries that the only solution is to “help people return to their former worries and labor…there is nothing more terrible than giving people paradise on earth.” Because earth is not paradise and our minds and bodies are not eternal. And there is some comfort in that.
