Some researchers 21 more than 1,300 children in different grades for a year. They asked both the kids and their parents to estimate how man

The first computers room-size behem
18、oths were referred to as “giant brains” or uelectronic 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
19、 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 dont flap theirwings. “Yet the princi
20、ples 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 push of necessity.The physical limits of conventional computer designs are within sight not today or tomorrow,but soon enough. Nanoscale circuits
21、cannot shrink much further. Todays chips are power hogs, running hot, which curbs how much of a chips 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 a

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 fr

M.Dr. Kelly points to Watson, the question answering computer that can play “Jeopardy!” and beat two human champions earlier this year. The I. B. M. s clever machine consumes 85,000 watts of electricity, while the human bra
