The field of ‘synthetic biology’ is in its infancy. We can ‘tweak’ the genetics of life forms – but billionaire entrepreneur Craig Venter only created ‘artificial life’ for the first time last year, christening his life form ‘Synthia’.
But experts working within the field believe that our expertise is out-accelerating natural evolution by a factor of millions of years – and some warn that synthetic biology could spin out of control.
It could lead, says Andrew Hessel of Singularity University, on Nasa’s research campus, to a world where hackers could engineer viruses or bacteria to control human minds.
Hessel believes that genetic engineering is the next frontier of computing.’This is one of the most powerful technologies in the world,’ says Hessel ‘Synthetic biology – the writing of life.’ ‘I advocate that cells are living computers and DNA is a programming language.’
‘I want to see life programmed and used to solve global challenges so that humanity can achieve a sustainable relationship within the biosphere,’ he says. It’s growing fast. It will grow faster than computer technologies.’ He predicts a world where we can ‘print’ DNA, and even ‘decode’ it. But he warned, in a speech at technology conference TXM, that viruses and bacteria send chemicals into human brains – and could be used to influence, or even ‘control’ their host.
A literal virus – injected into a ‘host’ in the guise of a vaccine, say – could be used to control behaviour.
Hessel warns that we ‘may have to learn how to counterattack’ against such weapons. Security expert Marc Goodman said, ‘Synthetic biology will lead to new forms of bioterrorism,’ and said, ‘Bio-crime today is akin to computer crime in the early Eighties, Few initially recognised the problem – but it grew exponentially.’
When billionaire entrepreneur Craig Venter ‘created life’ last year by adding synthetic DNA to a bacteria cell, Professor Julian Savulescu, an Oxford University ethicist, said: ‘Venter is creaking open the most profound door in humanity’s history, potentially peeking into its destiny.This could be used in the future to make the most powerful bioweapons imaginable.
