TECHNOLOGY BOON OR BANE

Humans have always had a worship and rejection bond with machinery. The worship and respect comes from the conveniences and benefits provided by the technology such as home appliances, cellular phones, and the internet. These benefits have greatly helped in improving the living status of its users, the common man. But as we know nothing is perfect, there are some disadvantages attached to the excess use of technology.

Authors of science fiction are among the first few people who raised a question about the excessive usage and dependence on technology. In 2001, C.Clake, in his book A Space Odyssey, created one of the most iconic evil robot characters: HAL who was sent on the mission to a Jupiter’s moon. For any technological failure, human error is the only reason. No machine can be developed or work on its own in absence of human element. In the story also, HAL considered human as the major threat to success of the mission. So in order avoid any error, the robot started murdering the crew members. The main human character identified HAL as the evil robot and disabled the machine to peacefully complete the mission.

The book raised the question of the viability of dependence of humans on machines. Is it right? Is it wrong? It made humans think practically and logically about the possible consequences of relying on gadgets created by mankind without respecting and understanding the value of humankind itself. For example, children have reduced outdoor games because of numerous gaming options available online. Their minds have become destructive and aggressive because of playing destructive games on the net. In the same manner every age group is getting affected in positive as well as negative manner because of improvement in technology. Thus a proper balance needs to be maintained so the disadvantages are overshadowed by the advantages of using technology.

Evil Robots or Evil Man

: Image via Wikipedia

Man has always had a love hate relationship with technology. The love comes from the convenience created by inventions such as the internet, the telephone or television. While the benefits of technology have improved the standard of living of millions many fear that man’s addiction to technology will be the eventual undoing of humanity.

Science fiction authors have been some of the first to raise the question of the potential destruct nature of reliance on machines. Arthur C. Clarke created perhaps the most iconic of the evil robot characters in his book 2001: A Space Odyssey. HAL the robot was created in Urbana, Il and implanted on a space craft to assist a crew on a vital mission to a moon of Jupiter. In the story, man has been contacted by aliens and a manned space mission is sent to meet with the visitors. HAL considers the mission to be far too important to allow unreliable elements to jeopardize it. So HAL does the only logical thing and attempt to eliminate anything that could cause the mission to fail.

Human error is the only thing that the computer can envision threatening the mission, so the computer begins to systematically murder the crew of the ship. Most are killed through suffocation while in hibernation. Others are killed in more creative ways such as being sent into space without a lifeline. The main character Dave is able to recognize that HAL has turned on his creators and is able to disable the robot and complete the mission.

The questions raised by the book and movie remain unanswered. Will the machines that mankind has created to improve the standards of living be the eventually undoing of human life? The question itself is flawed because the machines were created and programmed by man. HAL might have been the murderer in 2001, but as a creation of man the computer embodied human fears and failings.
