I would say most dangerous invention without a doubt is mobile phone. Though it is very useful at times but it is one thing that has lead to depreciation of value of privacy. People do not know their limits and invasion of privacy has become a common thing now.
@ vidhimayur..maobile phone??,.really?,..try to imagine a month ..even a week without your phone.
Yes, Deven without mobile phone it is difficult to imagine life but that us because we are all used to it now and I don't disagree to it but alongwith it's positive side it's negative point is that it invades our privacy.
