Older programming languages, such as Fortran and Delphi, will return based on the results of the language popularity index this month. Tiobe attributes their rise to the need to maintain a vital old system, still depending on them.
Fortran and Delphi come to the 10 best places in the index, with Delphi/Object Pascal evaluating the 10th and Fortran in the Tiobe Index for March 2025, published on March 10. ADA, 18th place and Cobol, in 20th place, are also a trend up. Fortran placed in 10th place only in January.
Tiobe CEO Paul Jansen considered it interesting to see how these furnaces “very old languages” slipped into the TOP 20. “Most of them are developed using these dinosaurs. Now that the last of the main developers of these systems are about to retire, companies avoid any risk and have decided to maintain existing systems and end them rather than replaced by newer systems based on more modern languages. These languages have evolved and are quite topical, he added.
