This varies from individual to individual.
When technological gadgets have got many to be ignorant of those around them. They also distract them from the primary duties and cause unsafe situations. Many children and adults can be obsessed by them.
In the other cases technology can work for us.
For example I am able to contact all my relatives who live around the world through my Iphone. I am able to communicate through emails, voice communications, pictures, and even videos.
During the recent Japanese tsunami disaster, I immediately got phone call from South East Asia the middle of the night about this danger. Then in seconds, I was able to call another relative in West Coast of US, and warn him about the possibility of a tsunami affecting him. I was in another part of the country several thousands of miles away. Then internet gave all other information we needed to know.
Technology is neutral and it is up to each individual on who should be the slave.
