The Internet is a giant international network of intelligent, informed computer enthusiasts, by which I mean, "people without lives." We don't care. We have each other.

Barry’s joke turns on a mock-definition: the Internet is framed as a community of “intelligent, informed” hobbyists, then punctured by the self-deprecating gloss “people without lives.” The punchline—“We don’t care. We have each other.”—reverses the insult into a claim of belonging. It captures an early popular perception of online culture as nerdy, obsessive, and socially marginal, while also acknowledging the genuine solidarity and companionship that networked communities can provide. The humor works because it simultaneously satirizes outsiders’ stereotypes and insiders’ willingness to embrace them.
