Hawking argues to alter human genes

Professor Stephen Hawking has argued humans need to change their genetic make-up or be left behind by smart computers that would take over the world, and that DNA should be modified to combat advancing technology.

"The danger is real that this [computer] intelligence will develop and take over the world," he said. Professor Hawking recommended "well-aimed manipulation" of human genes. Through this humans could "raise the complexity of ... the DNA [they are born with], thereby improving people". He conceded the road to genetic modification would be a long one but said: "We should follow this road if we want biological systems to remain superior to electronic ones."

Scientists are excited by the huge possibilities of genetic engineering and human interaction with machines, but ethicists urge caution. Ms Sue Mayer, director of the policy research group Genewatch, criticised Professor Hawking's remarks. "He is trying to take the debate about genetic engineering in the wrong direction," she said. "It is naive to think that genetic engineering will help us stay ahead of computers."
