The author of the sci-fi "Culture" novels contemplates how and why you might upload yourself to a computer - and the place of torture in his novels
Your latest book, Surface Detail, is based on the tantalising idea that we may one day choose to upload our minds to computers. How would that work?
The contents of your brain would be scanned down to the last molecule and electrochemical impulse and then translated non-destructively into digital form, so the essence of "you" is recreated inside a computer - your consciousness, personality and memories.
What would it feel like to exist in this world?
It would feel just like real life, or as different as it's possible to imagine
Just how implausible is the idea of creating a digital self?
Arguably, it's impossible. But in a sense it is just engineering. Given that the alien civilisations in my books who do this are thousands of years old, I'm assuming they'll have had time to develop it.
How do you create a faithful copy when we don't yet know what consciousness is?
That's the trouble: How do you get from a physical thing in the shape of a brain, neurons and synapses, to what we all experience as consciousness? It obviously exists in some form; each one of us is aware of being inside our bodies, with at least the appearance of free will. But where does it come from? I'm not claiming to have the answer, I'm just taking some interesting assumptions and running with them.
Would you describe yourself as a transhumanist, who wants to develop this sort of technology so we can live forever?
Not really. It all sounds a bit too narcissistic.
In your book, virtual minds can get sent to a virtual hell for bad behaviour. What gave you this idea?
Part of a science fiction writer's job is to think how we would manage to fuck up something so potentially cool and life-affirming - so virtual hells seemed almost as obvious as virtual heavens.
Do you think humans would create a virtual hell if they could?
Maybe. We simply don't know where we fall on the spectrum of behavioural possibilities that exist for sentient beings, though I've a sneaking suspicion we're near the nasty end.
Torture is a recurring theme in your books. Why is that?
You reflect the real world that you write within. I've been appalled at the suggestion from certain politicians and commentators that torture is OK, so long as it's us - the west - doing the torturing.
When do you think we might get the technology to download our brains?
I have no idea. Though maybe the internet will wake up tomorrow and go: "Hello, I'm here." After that, it's just a matter of time. Or not, of course. According to New Scientist, both AI and power generated by nuclear fusion are about 20 years into the future. But I've been buying the magazine for three decades, and you've always said that...
