Dick and William Gibson and movies such as Blade Runner and Ghost in the Shell project extremely ambivalent or cautionary attitudes towards know-how's impact on human society and identity.rapidprodesign Scientific advances and the discovery of recent concepts later allowed for powered flight and developments in medication, chemistry, physics, and engineering. The rise in know-how has led to skyscrapers and broad city areas whose inhabitants depend on motors to move them and their food provides. Communication improved with the invention of the telegraph, phone, radio and television. The late-19th and early-20th centuries noticed a revolution in transportation with the invention of the airplane and automobile.
