What technological advance has caused more harm than good?

Thinking (or the lack of it) will be our downfall. It does not matter if gunpowder had not been invented or if nuclear bombs were never dreamed off, people will always find ways to kill one another, as they have been since Cain and Able. People have said in this thread that 10% of the Russian army died during world war II, this was not just because of gunpowder alone. It was do to the way Russia's army was run under Stalin and his purges. And as a side not gunpowder as invented in China is not the same as what is used now which is smokeless propellant. Also it is not an explosive, it burns increasing pressures inside the barrel propelling the bullet.
