it was wars which brought mankind towards tech, then the fought when they kill each other they made peace now all those years they have been developing now its another war waiting for another peace and development . later on our next generations will call us dump that we were so slow in progress.Too bad the Asians in China have been dumb for the last 8000 years otherwise we'd have had computers and airplanes 500+ years ago. How was mankind so unlucky to have 100's of millions of smart people doing nothing for centuries. The apparent answer is luckily a few escaped Asia to the West and single handily moved everything forward. They were secretly in the background when trains, planes, automobiles, electricity, televisions, telephones, radio, elevators, steel/glass skyscrapers, and everything else was invented. We should all be grateful and in awe.
