Computers

As part
of the series Technology Our Saviour we have set out to discuss
the contribution of computers to our lives, past and present. The
computers, like the other instruments of technology we have discussed
so far – the electronic voting machine, the agricultural equipments
and techniques, and the GSM – do promise some great relief by
drastically reducing the avenues of corruption and minimizing the
effects of incompetence and other forms of human frailties that have
come to characterize our failed state.
In the
beginning was the brain that processes data on images, sounds,
feelings, etc, which we daily come across in our life. Though the
brain cannot be surpassed in processing such natural data (or
what we call signals) that is perceived by the body, it is
limited in its capacity to process and apply artificial one.
The brain, for example, quickly perceives gravity and, within
millionths of a second, processes it and concludes on the level of
danger it might pose to the body. Signals are immediately sent to
various muscles on what to do in order to maintain or restore safety
if the gravity poses any danger. The same thing when we see a lion or
a gang of armed robbers.
But ask
the brain to distribute 17 cows to five children – two boys and three
girls – with each male getting twice the share of a female. Here,
small as the data could be, even the brain of the genius will first
hesitate for some seconds or minutes before giving an answer. In most
cases it will fail. This is because the data does not belong to the
category of data it is naturally programmed to process. Its ability to
process these artificial data – or what we call information
– depends on its experience and genetic composition. This is not to
mention its limited power of retention. Ask it to list what it did on
a day exactly one year before and the brain will concede
impossibility.
Man has
recognized this limitation for long and has employed various means to
improve his processing and retention capabilities. The first
revolution in information technology was when man started to use
symbols to record his experience. He thus invented pictures, then
symbols and, recently, letters and figures to enable him handle facts,
real or imagined. To this category belonged the inscriptions of the
ancient empires of South America, the heliographies of Egypt, the
letters of ancient India, the Arabic and Arabic numerals, etc. He also
invented different media, at various times and places, for storage and
transfer of information particularly with the growth of government.
Thus, he inscribed, painted and wrote on stones, dried leaves, plates,
walls, etc.
But of
all his past inventions in information technology, paper was the most
remarkable. It permitted him to access, preserve and transfer
information using little space and cost. It was the second revolution
in information technology. Though, unlike human memory, paper could
not protect the information it carries against adulteration, it
nevertheless allowed the global spread of large quanta of information
beyond the local environment that stones and walls could afford. The
printing press, until recently, relied solely on paper to produce our
books, newspapers, reckoners, logbooks, and all documents of
transactions. There is little doubt that paper will remain a necessary
information medium for centuries to come.
The
third revolution came with the advent of data processing devises few
years ago. The power to program these devises has tremendously
increased the ability of mankind to process information to extents
that could not be imagined in the past. The power of arithmetic, for
example, was limited to few individuals even among the elite, and for
mathematics to much fewer. We had to rely on our memory of the
multiplication table to solve many problems while many permutations
may take a lifetime to solve. Things moved very slowly in the finance
and academic sectors as a result. Some transactions took weeks if not
months to execute and balancing of books was the nightmare of
accountants. And in the field of word processing, it would require
several years to write a book and several more to publish it. In the
same manner, it will take years to conceive and design a five-storey
building, generate its bill of quantities and analyse its tender. An
army of personnel and large spaces were thus required to do every job.
Though this provided employment, it made the price of goods and
services very expensive, thus promoting poverty.
Things
began to change with our power to program devises. The simple addition
machine, for example, enabled accountants to reconcile their daily
transaction records quicker, requiring only some few hours. Digital
technology improved things because it improved storage by introducing
memory and speed in the field of processing information. It always
amazed me to just see the square root of a figure or logarithm of a
number appear within a blink on the LCD of my first calculator in the
1970s, without using the log table. By then mega-frame computers have
been helping to process economic, scientific and engineering data of
many educational, financial and some few public institutions across
the world.
Mega-frame computers did not make the difference that would qualify
for a revolution though. Queues developed as many entries had to wait
for their turns. The processing itself was very slow. It is sweet now
to remember the index cards, the overnight punching, the editing, the
analysis, and the printing of results which would take a day or two to
complete. Up to my Masters degree in the mid-eighties, I never liked
courses that compelled me to use the computers at the Iya Abubakar
Computer Centre in Ahmadu Bello University.
But
everything started changing quickly in the mid 1980s when computers
began to be personalized. You can own a computer! That made the real
difference. Personal computers brought convenience and the speed of
their processing combined with the ever-increasing memory capacity has
triggered the third revolution in information technology. It started
in this country with importation of AMSTRAD and IBM personal computers
that were using starter discs and very limited memories in mid-1980s.
I remember then asking the computer to justify the margins of a
document would take as much time as is enough to boil water and brew
tea. Yet we were fascinated then by the fact that it is doing in
thirty minutes or so what would take a printer many days to
accomplish. Then came the era that was dominated by 286 and 386 PCs
that were much faster than our previous “Locoscripts”. And, finally,
Microsoft launched Windows 95 that simplified everything. In one
computer, using one keyboard, you have a whole world of choices in
processing information using various programs, including the ability
to browse the Internet, that egalitarian market place for exchange of
ideas and information that was never imagined before.
Suddenly, some of our frustrations with life in the developing
countries began to disappear. After initial resistance, the
conventional became old fashioned. Academicians who could not lay
hands on recent copies of journals, books and encyclopedias for over
ten years could do so now on the Internet. Schools and universities
can now process and keep record of students within a short time and
with minimum risk of error. Examination bodies are more efficient.
JAMB completes the marking of over 700,000 candidates in just a week.
Candidates can register online and download their results there. We
can participate in international discourse without attending seminars.
We can reach out to friends through emails without using the post
office or courier. Now with twitter, facebook and a variety of other
social networking products, the scope of our interaction is simply
explosive. What a relief!
But
nowhere is the impact felt more than in the service industry. The
banking sector is now wearing a very amiable face in terms of
services. New generation banks started transacting online, and behold,
the conservative older ones followed suite. We can now cash our
cheques anywhere, anytime, and withdraw cash conveniently using the
Automatic Teller Machine facility. We can also transfer cash quicker,
and, more importantly, safer. The competition in the industry is
intense. I could not have imagined this when I went to withdraw money
as little as N30.00 from my salary account as a lecturer in 1983. It
used to take hours.
Also,
engineers no longer need to depend on the drawing board and paper. The
AutoCAD has relieved architects and engineers of backaches and dirty
fingers arising from long tenures over drawing boards and association
with printing machines. Using their computers they can design readily,
draw quickly and print repeatedly without stays and stains. Quantity
surveyors can now measure designs promptly, generate bills and
certificates easily, and go to tender punctually. Life in the elite
private domain is generally easier, thanks to Silicon Valley.
But the
computer is yet to be appreciated by the public sector and certain
policies do severely limit the opportunities it offers. Employees in
the public sector have been reluctant in adopting computers because
they regard them as competitors and restraints. They have the capacity
to replace them and expose their corrupt practices. Much of the
corruption in this country is preserved today by this attitude. Ghost
workers cannot survive the computer age, for example, because workers
can easily be verified using a common database. And if e-government
were to be thoroughly adopted, then superiors can supervise the jobs
of their subordinates with astonishing ease. The public too may have
access, albeit small, to the inner activities of government. Thus, it
has taken over a decade before state governments in this country
started to computerize their payrolls. Other sectors of governments at
the federal and state levels are still unwilling to expose themselves
to the prudence and vulnerability of the computer. Forget about local
governments that they would wish computers would never reach them. But
reach them they would!
As a
result, access to information is difficult in the public sector. Wrong
decisions are taken as a result. I doubt if there is any government in
this country that can precisely say how many employees it has; nor
could it even give an accurate account of its teachers, their
stations, qualifications and so on, for example. Some may never do so.
Planning is, therefore, difficult, monitoring impracticable, and
result impossible.
The
crooks would definitely like an indefinite extension of the chance
they currently enjoy. That is why the politicians are against
electronic voting machine. It is very difficult teaching old dog a new
trick, the English say. But technology, as we have said before, even
in retrogressing countries like ours, is incipient, progressive,
pervasive and, finally, conquering. Those interested in making
fortunes in the future – our students and young graduates – must
befriend the computer and become its master. If they fail to do so,
they will one day find employment even in government difficult to get.
Fears
have been expressed on the prospects of increasing unemployment as
computers penetrate governments and companies. But this has always
been the case whenever a new technology is introduced. Our local
weavers in various households were mercilessly exterminated in the
1950s and 60s by the textile industry; the horse or donkey by the
automobile; the canoe by the boat; etc. Nobody, certainly not the
Nigerian Labour Congress, can spare our workers who even before the
advent of computers were merely wasting away in public office. No
amount of strikes will save them from the tide of technology, not even
the law. The determined among them, however, can upgrade his
capabilities and carve out another niche in the economy.
In
conclusion, I will declare that computers are not enemies, I believe,
unless we decide to make them so. For decades, they are the most
reliable friends I have made. Through their different software, they
make our work easier. We stay at home and execute several jobs. We
visit markets and make purchases from shops in Tokyo and London and
return within seconds using our Mastercard on the Internet without any
fly ticket or visa. Computers give us access to up-to-date information
without visiting libraries overseas. They increase the power of our
brains by doing what the latter may never do. They mitigate many of
the sufferings that our failed state inflicts on us. More importantly,
they represent avenues, through which our hope for a bright future
will be realized, a future that is competent, less corrupt and modern
in every sense. They are here to stay, with or without our permission.
They are welcome.
“Though
I am the last to arrive, I have come with what ealier ones could not
come with”, said the computer through the eloquent composition of the
compiler of Al-Atheer electronic library.
