John Naughton writes: The BBC Reith Lectures in 1967 were given by Edmund Leach, a Cambridge social anthropologist. “Men have become like gods,” Leach began. “Isn’t it about time that we understood our divinity? Science offers us total mastery over our environment and over our destiny, yet instead of rejoicing we feel deeply afraid.”

That was nearly half a century ago, and yet Leach’s opening lines could easily apply to today. He was speaking before the internet had been built and long before the human genome had been decoded, and so his claim about men becoming “like gods” seems relatively modest compared with the capabilities that molecular biology and computing have subsequently bestowed upon us. Our science-based culture is the most powerful in history, and it is ceaselessly researching, exploring, developing and growing. But in recent times it seems to have also become plagued with existential angst as the implications of human ingenuity begin to be (dimly) glimpsed.

The title that Leach chose for his Reith Lecture – A Runaway World – captures our zeitgeist too. At any rate, we are also increasingly fretful about a world that seems to be running out of control, largely (but not solely) because of information technology and what the life sciences are making possible. But we seek consolation in the thought that “it was always thus”: people felt alarmed about steam in George Eliot’s time and got worked up about electricity, the telegraph and the telephone as they arrived on the scene. The reassuring implication is that we weathered those technological storms, and so we will weather this one too. Humankind will muddle through.

But in the last five years or so even that cautious, pragmatic optimism has begun to erode. There are several reasons for this loss of confidence. One is the sheer vertiginous pace of technological change. Another is that the new forces at loose in our society – particularly information technology and the life sciences – are potentially more far-reaching in their implications than steam or electricity ever were. And, thirdly, we have begun to see startling advances in these fields that have forced us to recalibrate our expectations.[Continue reading…]
