From the article:
I'm almost convinced by Steven Landsburg's cost-benefit analysis showing that the spreaders of computer viruses and worms are more logical candidates for capital punishment than murderers are.
Professor Landsburg, an economist at the University of Rochester, has calculated the relative value to society of executing murderers and hackers. By using studies estimating the deterrent value of capital punishment, he figures that executing one murderer yields at most $100 million in social benefits.The benefits of executing a hacker would be greater, he argues, because the social costs of hacking are estimated to be so much higher: $50 billion per year. Deterring a mere one-fifth of 1 percent of those crimes - one in 500 hackers - would save society $100 million.
But since most creators of malicious software are less afraid of death than of boredom or embarassment, let's
make the punishment fit the crime.
I'm not certain if I agree with him and it's not practical, but I enjoy his vision of what do do with spammers.
