AI has gotten away without the self-restraints that scientists employ in the face of risks. How come?
Subscribe to enjoy similar stories.In December 2024, a number of scientists from around the world signed a four-page paper in Science that urged their own community to ensure that an entire class of organisms is never created. Their efforts managed to halt progress in a field that many of them had themselves been pursuing. This marked a rare moment in science when an entire field voluntarily abandoned the path it had been on because of the risks scientists saw ahead of them.The science in question was mirror-life, and the fact that such a moratorium was achieved raises the question of why similar outcomes were not achieved in the field of artificial intelligence (AI).
How was a small band of scientists able to pause progress in mirror-life when some of the most powerful voices in technology failed to do so in AI? For this, we need to first understand what mirror-life is. All complex naturally occurring biological molecules exist in one of two mirror-image forms, or chiralities. These forms are identical in every respect except that one cannot be superimposed on the other, much like our left hand cannot on our right.
DNA for example, exists as right-handed nucleotides and the proteins they encode are made up of left-handed amino acids. This pattern repeats in every microbe, plant and animal, and has done so for four billion years.A mirror organism would be identical to its natural counterpart, except that its orientation would be reversed. It would have left-handed nucleotides encoding right-handed proteins, and its every molecule would be a mirror image of its natural counterpart.
