Its true that technology has taken us to that point where we can even think of impossible but there are many counter-effects that human race is facing after this advancement in technology ...... wars , global warming , terrorism , time for family etc ........ Do u really think that technology is hurting us more than benefiting us 
?
?I think one of the main concerns for people in terms of technological advancements is the power it could give to the individual, destructive power that it. They say with moors law the speed of advancement increases by 2x. The same can be said for an individuals power to destroy the world, it is increasing at an equivalent pace. What happens when you can print guns in your bedroom or create a killer virus in your bedroom?
This is very pessimistic but constantly advancing technologically can have great dangers.
