Ever since the early days of modern computing in the 1940s, the biological metaphor has been irresistible. The first computers—room-size behemoths—were referred to as "giant brains" or " electronic brains," in headlines and everyday speech. As computers improved and became capable of some tasks familiar to humans, like playing chess, the term used was "artificial intelligence". DNA, it is said, is the original software.
For the most part, the biological metaphor has long been just that—a simplifying analogy rather than a blueprint for how to do computing. Engineering, not biology, guided the pursuit of artificial intelligence. As Frederick Jelinek, a pioneer in speech recognition, put it, "airplanes don’t flap their wings. "
Yet the principles of biology are gaining ground as a tool in computing. The shift in thinking results from advances in neuroscience and computer science, and from the prod of necessity.
The physical limits of conventional computer designs are within sight—not today or tomorrow, but soon enough. Nanoscale circuits cannot shrink much further. Today’ s chips are power hogs, running hot, which curbs how much of a chip’ s circuitry can be used. These limits loom as demand is accelerating for computing capacity to make sense of a surge of new digital data from sensors, online commerce, social networks, video streams and corporate and government databases.
To meet the challenge, without gobbling the world ’ s energy supply, a different approach will be needed. And biology, scientists say, promises to contribute more than metaphors. " Every time we look at this, biology provides a clue as to how we should pursue the frontiers of computing," said John E. Kelly, the director of research at IBM.
Dr. Kelly points to Watson, the question-answering computer that can play "Jeopardy!" and beat two human champions earlier this year. IBM’s clever machine consumes 85, 000 watts of electricity, while the human brain runs on just 20 watts. "Evolution figured this out," Dr. Kelly said.
Several biologically inspired paths are being explored by computer scientists in universities and corporate laboratories worldwide. One project, a collaboration of computer scientists and neuroscientists begun three years ago has been encouraging enough that in August it won a $21 million round of government financing. In recent months, the team has developed prototype "neurosynaptic" microprocessors, or chips that operate more like neurons and synapses than like conventional semiconductors.

文章第二段提到,“引导人们追求人工智能的是工程学,而不是生物学”。而“飞机不会拍打翅膀”是在说生物学无法解释计算。故填入biology。
