In an interview last month, Frank
Church, chairman of the Senate committee that is investigating the CIA, issued
an oblique but impassioned warning, that the technology of eavesdropping had
become so highly developed that Americans might soon be left with "no place to
hide". That day may have arrived. Newsweek has learned that the country’s most
secret intelligence operation, the National Security Agency, already possesses
the computerized equipment to monitor nearly all overseas telephone calls and
most domestic and international printed messages. The agency’s
devices monitor thousands of telephone circuits, cable lines and the microwave
transmissons that carry an increasing share of both spoken and written
communications. Computers are programed to watch for "trigger" words or phrases
indicating that a message might interest intelligence analysis, when the trigger
is pulled, entire messages are tape-recorded or printed out.
That kind of eavesdropping is, however, relatively simple compared with
the breakthroughs that lie ahead in the field of snoopery. Already it is
technically feasible to "bug" an electric typewriter by picking up its feeble
electronic emissions from a remote location and then translating them into
words. And some scientists believe that it may be possible in the future for
remote electronic equipment to intercept and "read" human brain waves.
Where such capabilities exist, so too does the potential for abuse. It is
the old story of technology rushing forward with some new wonder, before the man
who supposedly control the machines have figure out how to prevent the machines
from controlling them. |
It can be inferred that ______.
A:man will eventually be controlled by machines B:machines will eventually be controlled by man C:man is sometimes deceived by machines D:machines often rush into human brains
What does the writer think about machines with human-like ability
A:He believes they will be useful to human beings. B:He believes that they will control us in the future. C:He is not quite sure in what way they may influence us. D:He doesn't consider the construction of such machines possible.
