The best thing about the PKD episode (from "Galactic Pot-Healer") is that they're clearly goofing off on the Internet, or something much like it.

Leinster's "A Logic Named Joe" from 1946, which I keep mentioning, is not only the king hell champion of SFnal prescience with its networked home computers described as nearly physically identical to modern ones, but also manages to nail about a dozen actual uses and social phenomena revolving around them, including a character who basically Googles her old boyfriend and cyberstalks him. But gender relations in the story are very much mid-C20.
