I don't know if this should make me optimist or pessimist about the future!
Science is good, The use of it the right way is better.
Really I was confused when I saw this video the first time! there is a part of me that was proud of what us like human we have achieved in matter of technology and science, in the other hand I was afraid about what would be the consequence of this technology if it will be used against us like human by other human or if we lose control of this technology.
