I recently visited my old university town after being away for more than twenty years. It was a very unsettling experience; the town I saw was very different from the one I remembered, and those differences stirred up a lot of emotional turmoil.
I had uncomfortable visions of spending years coming to terms with those feelings, and with the deep subconscious issues that would probably be involved, about memories of my past and of days that could never be re-lived. It had all the makings of a great novel, until I mentioned it to Sue Gerrard, who said that more likely it was just a case of the uncanny valley.
She was right.
And that is why I’m now unlikely to write this century’s answer to À la recherche du temps perdu.
So what is the uncanny valley anyway, and why does it mean that the world will have to settle for this blog article instead of a literary masterpiece? The answer takes us through a surprisingly broad range of phenomena that individually look difficult to explain, but which might be explicable together as the effects of some simple cognitive processes.
