Technology is eating up all the manly things, such as sword skills, bravery, handicrafts and now they are saying that a printer would eventually make 3D human parts.
More human are being killed by unmanned aircrafts as you can shoot people from thousands of miles. Also think about the manual labor, for example, in poor countries such as India/Pak/Bangla Desh. They are being jobless at a fast pace. Rich countries are now on a fast pace to start the slavery era again and this time there will be no end. People will starve with hunger at the will of rich countires.
