Technological developments have created a new kind of separation in our society, experts and consumers. Experts have created smart nuclear bombs and understood the consequences. I do not want to think about who between both, will press the enter button of the third world war.

Technology has made a significant difference to the society. The question is, 'How far this difference be able to unite the society?’

There were so many forms of prehistoric technology.
Of those, men dig a few which fit into current society.

It wasn't technology that developed slowly, but collective knowledge of society and market demands.

Witchcraft had once been widely used before cursed by the society. I see today the society presumes technology will have a different treatment.

Like it or not, the governments of this world need to be well-prepared at the time when the alien races invade the earth. That will be the trigger. Nevertheless, the most dangerous thing will not be caused by the invaders, but by the ignorant opportunists amongst human who will start the last civil war.
