In the 1950s, the pioneers of artificial intelligence (Al) predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our housework. But as useful as computers are, they're nowhere close to achieving anything remotely resembling these early aspirations for human like behavior. Never mind something as complex as conversation: the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of tasks for a ten-month-old kid.
A growing group of Al researchers think they know where the field went wrong. The problem, the scientists say, is that AI has been trying to separate the highest, most abstract levels -of thought, like language and mathematics, and to duplicate them with logical, step-by-step programs. A new movement in AI, on the other hand, takes a closer look at the more roundabout way in which nature came up with intelligence. Many of these researchers study evolution and natural adaptation instead of formal logic and conventional computer programs, Rather than digital computers and transistors, some want to work with brain cells and proteins. The results of these early efforts are as promising as they are peculiar, and the new nature-based: AI movement is slowly but surely moving to the forefront of the field.
Imitating the brain's neural (神经的)network is a huge step in the right direction, says computer scientist and biophysicist Michael Conrad, but it still misses an important aspect of natural intelligence. "People tend to treat the brain as if it were made up of color-coded transistors", he explains, "but it's not simply a clever network of switches. There are lots of important things going on inside the brain cells themselves." Specifically, Conrad believes that many of the brain's capabilities stem from the pattern recognition proficiency of the individual molecules that makeup each brain cell. The best way to build an artificially intelligent device, he claims, would be to build it around the same sort of molecular skills.
Right now, the option that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow A1 rebels could turn out to be the only game in town.

B.are close to exhibiting humanlike behavior

Text 2
Life learning(sometimes called un-schooling or self-directed learning)is one of those concepts that are almost easier to explain by saying what it isn't, than what it is. And that's probably be-cause our own schooled backgrounds have convinced us that learning happens only in a dedicated building on certain days, between certain hours, and managed by a specially trained professional.
Within that schooling framework, no matter how hard teachers try and no matter how good their textbooks ,many bright students get bored,many slower students struggle and give up or lose their self-respect, and most of them reach the end of the process unprepared to enter into society. They have memorized a certain body of knowledge long enough to rush back the information on Tests,but they haven't really learned much, at least of the official curriculum.
Life learners, on the other hand, know that learning is not difficult, that people learn things quite easily if they're not compelled and forced, if they see a need to learn something, and if they are trusted and respected enough to learn it on their own timetable, at their own speed, in their own way. They know that learning cannot be produced in us and that we cannot produce it in others-no matter what age and no matter whether we're at school or at home.
Life learning is independent of time, location or the presence of a teacher. It does not require mom or dad to teach, or kids to work in workbooks at the kitchen table from 9 to noon from Sep-tember to June. Life learning is learner-driven. It involves living and leaming-in and from the re- al world. It is about exploring, questioning, experimenting, making messes, taking risks without fear of making mistakes, being laughed at and trying again.
Furthermore, life learning is about trusting kids to learn what they need to know and about helping them to learn and grow in their own ways. It is about providing positive experiences that enable children to understand the world and their culture and to interact with it.
51.1t is implied in the text that it is hard to _______ .
[A] carry life learning through
[B] tell the nature of life learning
[C] learn without going to school
[D] find a specially trained teacher
