The Kids' Whole Future Catalog, published in 1982, contains this illustration of future communication.
In the future, you won't have to learn a foreign language in order to talk to people from other countries. You'll just get out your electronic language translator. If you want to speak in Japanese, you'll just snap a tiny Japanese "memory capsule" into the machine. Then the machine will translate anything you say into that language. When you say "Hello" out will come "Konnichiwa" in perfect Japanese.
(Also, apparently in the future people will be cartoon caricatures of themselves.)
