Coders at Work: Reflections on the Craft of Programming

by Peter Seibel

Seibel: In 1974 you said that by 1984 we would have “Utopia 84,” the sort of perfect programming language, and it would supplant COBOL and Fortran, and you said then that there were indications that such language is very slowly taking shape. It's now a couple of decades since '84 and it doesn't seem like that's happened. Knuth: No. Seibel: Was that just youthful optimism? Knuth: I was thinking about Simula and trends in object-oriented programming when I wrote that, clearly. I think what happens is that every time a new language comes out it cleans up what's understood about the old languages and then adds something new, experimental and so on, and nobody has ever come to the point where they have a new language and then they want to stop at what's understood. They're always wanting to push further. Maybe someday somebody will say, “No, I'm not going to be innovative; I'm just going to be clean and simple, and I'm going to stick to it.” Pascal was started with that philosophy but then didn't continue. Maybe we'll get to a time when somebody will say, “Let's set our sights lower and really try to make something that's going to be stable.” It might be a good idea.
