Old Glories: Fortran and Cobol are still among the world's most popular programming languages despite being almost 70 years old. They're certainly overachieving, but for entirely different reasons, and neither seem unwilling to go out of fashion as new technological advancements like AI keep old skills relevant. The May 2024 edition of the TIOBE Index includes a couple of surprising results, placing two of the most ancient programming languages among the top spots in popularity among developers.
The TIOBE Index, which gathers data from 25 high-ranked search engines, is updated monthly and primarily focuses on Turing complete languages. As a result, HTML and other markup languages such as XML are excluded, despite their popularity as "coding" technologies. According to the latest TIOBE Index , Python, C, and C++ are the three most popular programming languages among developers.
Fortran, a compiled language originally created by IBM in 1957, is especially suited to numeric computation and scientific computing tasks. According to the index, this ancient language is still the 10th most popular programming technology. Fortran reentered the top 10 after more than 20 years, and TIOBE Software CEO Paul Jansen has provided some explanations for this seemingly odd situation.
The TIOBE Index simply "publishes what has been measured," and Fortran is apparently the subject of more than a thousand books available on Amazon. New, "cool" languages such as Kotlin and Rust barely hit 300 books.
