A welcome that stuck
Brian Kernighan’s early-1970s introduction to the B language includes a “hello, world” example. The Bell Labs archive associates the report with January 1973; earlier histories sometimes use 1972. We use the broader period rather than pretending there was one universally agreed “Hello, world!” event.
The example became widely familiar through The C Programming Language, the 1978 book by Kernighan and Dennis Ritchie. It remains a small, satisfying first test in many programming lessons.
Our version of the tradition
Our homepage greeting is a nod to that feeling: type something, try something, and see a result. You do not need to learn a programming language to begin exploring AI. A carefully checked first prompt is a good start.
