Technology tends to follow necessity. Throughout history humans have continuously come up against challenges. Plagues, wars, natural disasters, climate change. All these influences haven driven technological advancement.
You could also argue that the dreams of man have also been challenges within themselves. To have a burning desire in your heart means to be challenged by following it every day.
It is from these challenges that technology has risen. While World War II induced a horrible loss of human life, there remains the fact that it increased the development of technology across the world.
Most people see problems and disadvantages as just that, negative denominators on successful change. But it couldn’t be further from the truth. The very fact those disadvantages exist is to provide a country or person with the drive, the antagonist to contend with. The very thing that ‘hinders’ the change is the goal to shoot for.
