[00:03.77]2002 Text2
[00:07.50]Since the dawn of human ingenuity,
[00:10.22]people have devised ever more cunning tools
[00:13.05]to cope with work that is dangerous,
[00:15.66]boring, burdensome, or just plain nasty.
[00:20.83]That compulsion has resulted in robotics
[00:24.27]--the science of conferring various human
[00:26.59]capabilities on machines.
[00:29.12]And if scientists have yet to create
[00:31.54]the mechanical version of science fiction,
[00:34.27]they have begun to come close.
[00:37.09]As a result, the modern world
[00:39.51]is increasingly populated by intelligent gizmos
[00:43.16]whose presence we barely notice
[00:45.27]but whose universal existence
[00:47.60]has removed much human labor1.
[00:50.42]Our factories hum to the rhythm of robot assembly arms.
[00:54.87]Our banking2 is done at automated3 teller4 terminals
[00:58.00]that thank us with mechanical politeness for the transaction.
[01:03.24]Our subway trains are controlled by tireless robot-drivers.
[01:07.98]And thanks to the continual miniaturization of electronics
[01:12.22]and micro-mechanics,
[01:14.03]there are already robot systems
[01:15.94]that can perform some kinds of brain
[01:17.97]and bone surgery with submillimeter accuracy
[01:22.01]--far greater precision than highly skilled physicians
[01:25.02]can achieve with their hands alone.
[01:28.08]But if robots are to reach the next stage of
[01:30.72]laborsaving utility,
[01:32.53]they will have to operate with less human supervision
[01:35.96]and be able to make at least a few decisions
[01:38.48]for themselves--goals that pose a real challenge.
[01:42.62]"While we know how to tell a robot
[01:44.19]to handle a specific error,"
[01:46.50]says Dave Lavery, manager of a robotics program at NASA,
[01:51.34]"we can't yet give a robot enough 'common sense'
[01:54.77]to reliably interact with a dynamic world."
[01:58.41]Indeed the quest for true artificial intelligence
[02:02.25]has produced very mixed results.
[02:05.67]Despite a spell of initial optimism in the 1960s and 1970s
[02:10.91]when it appeared that transistor5 circuits
[02:13.23]and microprocessors6 might be able to copy the action
[02:16.47]of the human brain by the year 2010,
[02:19.99]researchers lately have begun to extend
[02:22.71]that forecast by decades if not centuries.

[02:26.95]What they found, in attempting to model thought,
[02:30.17]is that the human brain's roughly one hundred billion
[02:33.09]nerve cells are much more talented
[02:36.12]--and human perception far more complicated
[02:38.94]--than previously7 imagined.
[02:41.26]They have built robots
[02:42.67]that can recognize the error of a machine panel
[02:45.29]by a fraction of a millimeter in a controlled
[02:48.22]factory environment.
[02:50.43]But the human mind can glimpse a rapidly changing scene
[02:54.16]and immediately disregard the 98 percent that is irrelevant,
[02:58.70]instantaneously focusing on the monkey
[03:01.02]at the side of a winding8 forest road
[03:04.05]or the single suspicious face in a big crowd.
[03:07.77]The most advanced computer systems on Earth
[03:10.50]can't approach that kind of ability,
[03:12.82]and neuroscientists still don't know quite how we do it.
