Malcolm Gladwell 2: The strange tale of the Norden bombsight (transcript)
Summary
This is the article that Japanese people must read.
It's because the article uses the Norden bombsight as one example.
On August 6, 1945, was the day when 140 thousand people were killed by a B-29 bomber called the Enola Gay. It used the Norden bombsight and dropped a very large atomic bomb on Hiroshima Japan.
Was this God’s will that the amount of suffering in any kind of war was reduced to as small an amount as possible?
No one knows the true answer because the victim might be more increased if it wouldn't occur.
However, my opinion is that this "Got’s will" will be the human ego. The thought that the amount of suffering in any kind of war can be reduced to as small an amount as possible is the human arrogance.
People just wanted to protect themselves.
Having a gun is also the same thing.  People say that they don't want to harm others, but victims are increasing but they hope to have a gun. They want to protect themselves.
The product is created to protect people, but it harms people. One day, this is absolutely useful is thought though it harms people or it's never used.
There's the story that is strange.
