Taking the Fi out of Sci





Wow:

2050 - and immortality is within our grasp

...

'If you draw the timelines, realistically by 2050 we would expect to be able to download your mind into a machine, so when you die it's not a major career problem,' Pearson told The Observer. 'If you're rich enough then by 2050 it's feasible. If you're poor you'll probably have to wait until 2075 or 2080 when it's routine. We are very serious about it. That's how fast this technology is moving: 45 years is a hell of a long time in IT.'

Pearson, 44, has formed his mind-boggling vision of the future after graduating in applied mathematics and theoretical physics, spending four years working in missile design and the past 20 years working in optical networks, broadband network evolution and cybernetics in BT's laboratories. He admits his prophecies are both 'very exciting' and 'very scary'.

He believes that today's youngsters may never have to die, and points to the rapid advances in computing power demonstrated last week, when Sony released the first details of its PlayStation 3. It is 35 times more powerful than previous games consoles. 'The new PlayStation is 1 per cent as powerful as a human brain,' he said. 'It is into supercomputer status compared to 10 years ago. PlayStation 5 will probably be as powerful as the human brain.'

The world's fastest computer, IBM's BlueGene, can perform 70.72 trillion calculations per second (teraflops) and is accelerating all the time. But anyone who believes in the uniqueness of consciousness or the soul will find Pearson's next suggestion hard to swallow. 'We're already looking at how you might structure a computer that could possibly become conscious. There are quite a lot of us now who believe it's entirely feasible.

'We don't know how to do it yet but we've begun looking in the same directions, for example at the techniques we think that consciousness is based on: information comes in from the outside world but also from other parts of your brain and each part processes it on an internal sensing basis. Consciousness is just another sense, effectively, and that's what we're trying to design in a computer. Not everyone agrees, but it's my conclusion that it is possible to make a conscious computer with superhuman levels of intelligence before 2020.'

He continued: 'It would definitely have emotions - that's one of the primary reasons for doing it. If I'm on an aeroplane I want the computer to be more terrified of crashing than I am so it does everything to stay in the air until it's supposed to be on the ground.

...

'We can already use DNA, for example, to make electronic circuits so it's possible to think of a smart yoghurt some time after 2020 or 2025, where the yoghurt has got a whole stack of electronics in every single bacterium. You could have a conversation with your strawberry yogurt before you eat it.'

In the shorter term, Pearson identifies the next phase of progress as 'ambient intelligence': chips with everything. He explained: 'For example, if you have a pollen count sensor in your car you take some antihistamine before you get out. Chips will come small enough that you can start impregnating them into the skin. We're talking about video tattoos as very, very thin sheets of polymer that you just literally stick on to the skin and they stay there for several days. You could even build in cellphones and connect it to the network, use it as a video phone and download videos or receive emails.'

...

The next age, he predicts, will be that of 'simplicity' in around 2013-2015. 'This is where the IT has actually become mature enough that people will be able to drive it without having to go on a training course.

'Forget this notion that you have to have one single chip in the computer which does everything. Why not just get a stack of little self-organising chips in a box and they'll hook up and do it themselves. It won't be able to get any viruses because most of the operating system will be stored in hardware which the hackers can't write to. If your machine starts going wrong, you just push a button and it's reset to the factory setting.'

Pearson's third age is 'virtual worlds' in around 2020. 'We will spend a lot of time in virtual space, using high quality, 3D, immersive, computer generated environments to socialise and do business in. When technology gives you a life-size 3D image and the links to your nervous system allow you to shake hands, it's like being in the other person's office. It's impossible to believe that won't be the normal way of communicating.
There's so much mindfood here, it's a glut. So I'm just gonna be really general -

I can believe all this only because, to my puny mind, it seems to take the trajectory we're moving on further along its natural path. And also we're all aware at how certain types of technology - computer power in particular - seems to increase at an exponential rate. I think that these predictions beggar 2 questions:

1. Will we be around to make this happen? It kind of assumes that we don't knock ourselves back by letting the environment collapse around us or wiping ourselves out in a war. The odds of both happening in the near future are not unreasonable. But that's what I like about this kind of science writing - there's an innate optimism in all its assumptions of untramelled progress.

2. Are we equipped to deal with the real-life philosophical questions this kind of technology forces on us? Once you start creating forms with their own consciousness, once you start instilling emotions into machinery, once you start manipulating life from before conception - then you're entering realms of responsibility no human has has ever had to deal with before. They may have wanted to, but they never had the chance.

Do we have the equipment to handle this? Are we ready to accept other forms of consciousness as our equals - or will we regard them as our servants? And what then? And how soon before reality as we understand it ceases to have any practical sense?

Paging Plato, Socrates, Aristotle - we really need you right about now.
