has a computer done more harm than good?

a computer is like any other tool, only as useful as the way you use it. Look at drugs:

Heroin great for keeping people still while doing major surgery, let it take control of your life and its a major problem. the same with most drugs.

Guns, bows and arrows very useful for putting food on the table (ie meat) in the old days, but terrible when used in a war.

Cars great transport, but used wrong, like the hands of a drunk or an idiot, and they kill people in wholesale lots.
