own EPCs. Rather than preempting these efforts, an American or
international EPC could aid them, thereby multiplying the benefits of
the original organization and forestalling fears of electronic
imperialism.
The EPC could have a domestic version, too. Because of lower
communications cost, the Home Corps (a friend’s phrase) might take more
chances helping nonexperts without credentials. A gifted high school
writer on Chicago’s South Side might tap out short stories on a school
computer, for example, and a famous author across town might zip the
files back, with comments easily inserted electronically. The two might
meet a few times in person, then carry on via computer without the
hassles and menace of urban travel. Likewise, an Evanston business
executive might volunteer help to a businesswoman in a small town many
miles away.
The most urgent need for EPC-style assistance, however, is in the Third
World, where, because of technical backwardness, so many are starving.
The idea isn’t so farfetched. In fact the Third World is already
enjoying some similar help in a small way.
The CARINET computer network links the United States, the Caribbean,
Southeast Asia, and Africa. Long before harvest time a Jamaican farmer
can learn how promising a market there’ll be for his crop in the United
States—or an African potter can find out how to make a ceramic insulator
for his local phone company. Jerome Glenn, an official with Partnership
for Productivity International, the Washington-based group behind
CARINET, says the answers often come in just a day.
“Mail takes too long and Telex is too expensive,” notes another Peace
Corps alumnus, now heading a nutrition group that works to export U.S.
technical savvy through more conventional means.
Many foreign aid and computer experts have similar feelings. The
technicians, sure enough, are far ahead of the politicians. One of the
most distinguished technicians of them all—Arthur C. Clarke, the father
of the communications satellites—describes the EPC proposal as “an
excellent idea.”
Reaction from Third World countries has been favorable. Naren Chitty, a
Sri Lankan diplomat, says the concept is “a positive approach to
technology transfer” in “these days when ‘electronic imperialism’ is a
catchword.” And a Saudi Arabian communications specialist likewise
advocates computer and networks for the Third World. He says: “I had a
terrible argument with this Indian man who said, ‘My people are starving
to death, and you talk about microcomputers.’ And I said, ‘It’s because
of food distribution—the food isn’t getting there. The reason they’re
starving is that they don’t have the benefits that computers could
bring.’”

POSTSCRIPT:
Just as I was finishing this book I heard from my friend the Saudi
Arabian communications specialist, Omar Alfarouq. Omar says EPC-style
efforts are already realities in some places—not just dreams.
Via MCI Mail from California, he told me of “the creation of an
Information network throughout Third World, accessible within our own
cultural reference.
“It has bloomed under sponsorship Gulf Cooperation Council; data banks
for farmers, medical workers in Arabic accessible by personal computer
from Oman to Kuwait; anyone can access though it is most often done
through local Ministry of Information office; will be tied in with
university information systems. It’s moving _alhamdullilah_ [thanks to
God].” Omar says the idea for this net goes back to 1981.
He continues:
“Your Electronic Peace Corps is alive and well and working wonders in
Africa at present time, am surprised you are not there doing it. I just
returned, am here to regroup, energy burn-out terrible. For example
Sahel 84 is a French group 30, lorries w/ food/medicine, one light plane
with ground station tied into INMARSAT; satellite shows ground picture
where people have sunk down hopeless in endless reaches of Niger, Mali
etc., guides convoy to place of need; communication link back to Paris
advises of further food/medicine need, diagnostic advice, these helped
while other abandonees are being located. That’s Sahel 84.
“Mobility 84 is British with land-rover as ground station with a
computer, word-processing, works in west central Africa, put together by
Alan Benjamin of CAP software in England, Contact him he is doing what
you are brooding about.
“Medecines sans Frontreres also has sat-data link to Paris from its camp
south Soudan just over border from Ethiopia for Tigre refugees; Tigre
people in terrible shape. Data banks can _insha’allah_ [if God wills]
save Soudan from becoming like Ethiopia—it’s getting that way fast.
Contact Gordon MacRae, deputy editor of Economist in London for further
up-dates, also Jim Grant of UNICEF.
“Congratulations on yr book. But the real point of data exchange is its
tremendous humanitarian impact which is so desperately needed in places
that will never ever see anything like a telephone. Timely forecasting
can prevent Third World suffering. Or even in America. That’s your next
book. See you in Addis.... _wa salaam_ [good-bye], Omar.”
Americans invented the transistor, the microchip, personal computers;
now if only we’ll catch up with the British, French, and Saudis in
bringing the technology to the people who most need it!
Thanks!
My Victor 9000 and Panasonic printer ideally could spew out a list of
people to thank—starting with those who most deserved it.
As a mere human, however, I don’t feel up to ranking anyone other than
to mention the big nine:
● Michael Canyes, a professional computer consultant who gave dozens of
hours of his time in the best user-to-user tradition.
● Mack Truslow, an old friend on whom I cruelly inflicted page after
page of rough drafts.
● David Fay Smith, a writer/computer expert who was the technical editor
and who himself is the author of _A Computer Dictionary for Kids and
Other Beginners_ (Ballantine, $9.95).
● Don Carrol, the cover artist.
● Robert B. Wyatt, editor-in-chief of Ballantine Books, who had the
imagination and courage to make this a mass-market paperback.
● Richard McCoy, his assistant.
● Frank Lavena, the copyeditor.
● Pat Ehresmann of the Random House production staff, who is an
innovator in the spirit of this book.
● Ruth Aley, a legendary literary agent whom writers have been thanking
for decades—perhaps beginning with Irving Stone.
● Berenice Hoffman, her partner on this project. Shopping for a computer
while I was writing _The Silicon Jungle_, she was a perfect test
reader.
In addition I’ll thank the Fairfax County Public Library System,
especially the Fairfax City branch’s business room. Thanks also to the
Martha Washington, George Mason, and Sherwood branches. (Computerized
databases will never do away with first-rate librarians.)
With the understanding that my list isn’t necessarily complete, here are
other people to whom I’m grateful:
