Our way of dealing with kids coming in over Arpanet was to socialize them. We all participated in that. For example, there was a command you could type to tell the system to shut down in five minutes. The kids sometimes did that, and when they did we just cancelled the shutdown. They were amazed. They would read about this command and think, surely it’s not going to work, and would type it—and get an immediate notification: ‘The system is shutting down in five minutes because of . . . ’

It sounds like chaos.

Except it wasn’t, you see. There was always a real user, who would just cancel the shutdown and say to that person, ‘Why did you try to shut the machine down? You know we’re here using it. You only do that if there’s a good reason.’ And the thing is, a lot of those people felt outcast by society—they were geeks; their families and their fellow students didn’t understand them; they had nobody. And we welcomed them into the community and invited them to learn and start to do some useful work. It was amazing for them not to be treated as trash.
