I wouldnt call technology evil or a manna. Technology is but a tool. How one uses it is what matters in the end.
Take a holistic view of the world, you will see what technology has done to the human race. The quality of life has definitely improved, compare today with the days before industrial revolution. There still was life, people were living a life as happy or as painful as it is today, Technology just magnified it working as a multiplier effect.
Killing has become as sophisticated as has cure. Healthcare, Power generation has been benefited from nuclear technology and so has it become a terminator of life forms. Airplanes have made this planet smaller while Bin Laden discovered newer uses with these crafts.
To sum it up, Technology has had more of positive influence on human race than bad.
