One weekday in 1988 I was waiting in line to order at a lunch counter in Kendall Square, Cambridge, Massachusetts (or it might have been Au Bon Pain by then). In front of me were two MIT guys who were talking quickly and nervously about something that was going very wrong on the Internet. The problem was the first software worm, written by Robert Morris, who is now at MIT himself. His father, one of the creators of the Unix operating system, has died.
