The annual “top of the 2020 pops” for programing languages is out at [https://www.tiobe.com/tiobe-index/](https://www.tiobe.com/tiobe-index/) While Python ranked third overall, it won the “language of the year” award due to showing the fastest annual growth of 2.01%, narrowly beating fourth placed C++ which grew 1.99%. Prolog was ranked at 29 with 0.48% growth while Lisp was ranked 36 with 0.37% growth – which I think is not bad for “classical languages” in a pop ranking. The TIOBE index is obviously [flamebait](https://developers.slashdot.org/story/21/01/10/035241/python-named-programming-language-of-the-year-by-somewhat-dubious-tiobe-index), based on how many people searched via Google etc for solutions to problems programming in whatever. One of the few smart comments on slashdot was this means confusing languages have an advantage. But it does raise the old debate about what can be done to make Prolog more popular. ---

I don’t think 0.48% is growth. It’s just a current rank against other languages. It doesn’t show if the Prolog’s popularity is growing. It would be interesting if anybody has stored a historical TIOBE Prolog’s rating. ---

There are problems with the TIOBE method. Interestingly, arguing over it has been popular ever since it was invented. The question of popularity is what the Germans would call “komisch”. “Well, Hitler was popular!” Is it fair to bring dictators into a discussion of programming languages? We should ask someone from the Python crowd. Anecdotal evidence, collected by me, suggests that the relevance of the programming language is either a) shrinking; or b) was never a thing. I don’t have historical data going far back enough to be able to tell which one of the two, or both. What I can tell with high confidence is: in a brave new world of serverless cloud-native microservices, an ancient and all but forgotten programming paradigm has taken over the software world. Its second coming was prophesied in a [dry, academic treatment of programming languages](http://james-iry.blogspot.com/2009/05/brief-incomplete-and-mostly-wrong.html): > At a neighborhood Italian restaurant Rasmus Lerdorf realizes that his **plate of spaghetti** is an excellent model for understanding the World Wide Web… [emphasis mine] Which programming language, which technology will tame and harness the power of spaghetti? Will this trigger the technological singularity or is it a reincarnation in an endless cycle of transmigration and rebirth? ---

Thanks for the link to the satirical history of programming languages (which I think shows a lot of underlying knowledge). My favourite taxonomy of programming languages is the joke [Programming Language Checklist](https://www.famicol.in/language_checklist.html) which has “imperative” but not “declarative” in the opening choice. ---

Reminds me of a post by Jan Burse in spring 2017 A recent analysis shows that Prolog seems to become most popular language in the future. Among the current top contenders are Java, Python, … But they are drastically loosing turf as Edward J. Goodwin from the software institute in New Albany, Indiana told. Another commenter involved with machine lerning told us, we run all our prediction models and it seems pretty clear that Prolog will be the raising star in the next 6-18 Months. Meanwhile GitHub has announced it might default the extension .p to Prolog in the future. Many schools started buying the Art of Prolog books, which is currently out of stock at Amazon. A definitive explanation for this surge of Prolog has not yet been found. Professor Sally Popcorn from the Applehart University for Lingustics and Philosophy said, we speculate that the programming language has a genetic advantage in that it provides the logical variable. A concept that was more than 2000 years ago introduced by Aristoteles. She cited various studies that showed that logical variables have clearer semantics, support unicode, dont need a preprocessor, have a parser friendly syntax and are less prone to segmentation faults.

The Art of Prolog was “open access” at [The Art of Prolog, Second Edition](https://mitpress.mit.edu/books/art-prolog-second-edition) a short while ago (I availed myself to a free pdf) but seems to have been made “commercial only” again. A freely available book I really like is Robert Kowalski’s Logic for Problem Solving [http://www.doc.ic.ac.uk/~rak/papers/LogicForProblemSolving.pdf](http://www.doc.ic.ac.uk/~rak/papers/LogicForProblemSolving.pdf) which unfortunately doesn’t use novice-friendly Prolog syntax (a common problem with the “classics”). ---

Alone the fact that TIOBE is supposedly an acronym for “The Importance of Being Earnest” (have you read the play?) makes me strongly suspect that the whole thing is just a masterclass troll move. 🙂 ---

I know, and it was a good one. I tried to hide it a bit by writing “spring 2017”. There was even a response, something along the lines of “Oooh Jan…” Best, Matthias ---

Strange. When I visit [swi-prolog.org](http://swi-prolog.org) and then Community, then old mailing list/Google group, then I use the search function with tiobe, I can see two posts (rather threads), yours and one of Annie. And if I select yours, I can see a response “Oh you!” from “steph…” Nondeterministic behavior all over the place ---

Well, although I personally feel some excitement about that programming languages rankings, much more interest for me is to gain knowledge which companies or business domains have chosen which language and why. Especially if the language of question is not mainstream it is cool to know which problem a company tackles by using this language. This was true in my Smalltalk days, to learn that Smalltalk was on interest at JP Morgan was cool. But unfortunately, for Prolog I have nearly no information where Prolog is used (beside academic research). Sometimes I get the impression that “people who love language X, where X is not C/C++, Java/JS or Python” coming from academic and coming from commercial use don’t find together. But only my personal impression. Cheers Hans
