The possibility of digitising the human mind is one of those questions that will only be closed by its successful achievement, I think; there’ll always be an argument for its possibility, because the only way to disprove it would be to quantify how personality and mind actually work, and if we could quantify it, we could probably work out a way to digitise it, too. (That said, if someone can chop a hole in my logic train there, I’d be genuinely very grateful to them, because it’s a question that’s bugged me for years, and I haven’t been able to get beyond that point with my bootstrap philosophy chops.)

Philosophical digressions aside, low-grade not-quite-proof-of-concept stuff seems to be the current state of the industry. Via NextNature, New Scientist discusses a few companies trying to capture human personality in computer software:

Lifenaut’s avatar might appear to respond like a human, but how do you get it to resemble you? The only way is to teach it about yourself. This personality upload is a laborious process. The first stage involves rating some 480 statements such as “I like to please others” and “I sympathise with the homeless”, according to how accurately they reflect my feelings. Having done this, I am then asked to upload items such as diary entries, and photos and video tagged with place names, dates and keywords to help my avatar build up “memories”. I also spend hours in conversation with other Lifenaut avatars, which my avatar learns from. This supposedly provides “Linda” with my mannerisms – the way I greet people or respond to questions, say – as well as more about my views, likes and dislikes.

A more sophisticated series of personality questionnaires is being used by a related project called CyBeRev. The project’s users work their way through thousands of questions developed by the American sociologist William Sims Bainbridge as a means of archiving the mind. Unlike traditional personality questionnaires, part of the process involves trying to capture users’ values, beliefs, hopes and goals by asking them to imagine the world a century in the future. It isn’t a quick process: “If you spent an hour a day answering questions, it would take five years to complete them all,” says Lori Rhodes of the nonprofit Terasem Movement, which funds CyBeRev. “But the further you go, the more accurate a representation of yourself the mind file will become.”

It’s an interesting article, so go take a look. This little bit got me thinking:

So is it possible to endow my digital double with a believable representation of my own personality? Carpenter admits that in order to become truly like you, a Lifenaut avatar would probably need a lifetime’s worth of conversations with you.

Is that a tacit admission that who we are, at a fundamental level, is a function of everything we’ve ever done and experienced? That to record a lifetime’s worth of experiences and influences would necessarily take a lifetime? Emotionally, I find myself responding to that idea as being self-evident… and it’s the intuitive nature of my response that tells me I should continue to question it.
