Probably. But the kid would socialize while doing so, learn the skills of mastery, and basically learn how to manage their time in a fulfilling way. Kids at Sudbury schools often do spend a great deal of time on the computers, but that is rarely, if ever, the only thing they do. What they are learning to do is how to incorporate computers into daily life, mastering the machine.

in the process learning about architecture, collaboration, resource management, economies of scale, and oh yeah, the ability to create a full Turing machine… if this comment was supposed to be disparaging, you’d need a different example ;-)
