Technology is it a threat?

Technolgy has always been a great advance and a great threat but we as humans always disregard the harm because technology makes life easier for us and in away protects us. For example Nuclear power when it was created was thought to be the greatest Technolgy and sooner or later we realized it is the biggest threat to human life that was ever created . But we never think of the consequences and what might happen. Even though it threatens us we are not going to stop with technology because we are so use to it and most technology is part of our daily lives,
