From Electronic Life:
We will be less inclined to regard computer crime as clever. Most computer crime is rather stupidly simpleminded. The welfare worker who programs the computer to make out checks to himself isn't smart. (If he were smart, he wouldn't send the checks to his own house.) Nor is computer crime innocent. The disgruntled employee who programs a bomb in the computer to shut down the system a month after he leaves is no better than an arsonist.

Further, as more people become skilled in the use of computers, the vulnerability of individuals will increase. It's one think to read that someone ripped off the phone company. It's another thing to have an argument with you neighbor, who then taps into data banks and destroys your credit rating, eliminates bank records of your mortgage payments, or orders your car repossessed.

Finally, age will cease to be a mitigating factor. The ability of some kid to shut down a large computer system in another city or another country for a week or two will simply be intolerable - no matter how much he explains that he didn't mean to do it. After a period of education in these matters, there will be several highly publicized cases in which twelve-year-olds go to jail. Everybody's going to feel uncomfortable about it, but society won't really have a choice.
