Technology is Double edged sword. If not used for the right purpose is can certainly ruin us. I will give you a number of examples to prove this.

1.) Human Cloning is banned in 70 Countries because of its ethical consequences.
2.) Nuclear Bombs are the most evil creation of man kind but the same Nuclear Power is used to generate electricity.
3.) Technology enables us to watch a live game thousands of miles away. The same technology can be used to spy on someone from thousands of miles away.

Thus technology is good & bad both it all depends upon the user. In the most easy to understand language technology gave us the Blender its our choice whether we grind vegetables in it or put our finger in it to chop it off.
