The New York Times has a good article today by Cornelia Dean about our growing need (and ill-preparedness) to consider the long-term impact of new technologies, particularly geoengineering and nanotechnology. Excerpt:
with iron, in hopes of encouraging carbon-absorbing blooms of plankton.
Meanwhile, researchers elsewhere are talking about injecting chemicals
into the atmosphere, launching sun-reflecting mirrors into stationary
orbit above the earth or taking other steps to reset the thermostat of
a warming planet.
This technology might be useful, even life-saving. But it would
inevitably produce environmental effects impossible to predict and
impossible to undo. So a growing number of experts say it is time for
broad discussion of how and by whom it should be used, or if it should
be tried at all.
Similar questions are being raised about
nanotechnology, robotics and other powerful emerging technologies.
There are even those who suggest humanity should collectively decide to
turn away from some new technologies as inherently dangerous.
“The complexity of newly engineered systems coupled with their
potential impact on lives, the environment, etc., raise a set of
ethical issues that engineers had not been thinking about,” said
William A. Wulf, a computer scientist who until last year headed the
National Academy of Engineering. As one of his official last acts, he
established the Center for Engineering, Ethics, and Society there.
Rachelle Hollander, a philosopher who directs the center, said the new
technologies were so powerful that “our saving grace, our inability to
affect things at a planetary level, is being lost to us,” as
human-induced climate change is demonstrating.
