Most people believed, incorrectly as it turned out, that Ada and PL/1 would dominate the future. But I was more interested in Prolog and Smalltalk. Prolog was the answer, but I didn't know what the question was. I'll talk about how we grew a programming language, and what the main factors were in spreading the language. I'll relate my personal experience with Erlang to broader developments in programming and try to see how the two fit together. I'll also take a peep into the future and speculate about where computing is going.
