Fortran, once the gold standard of programming languages, has seen a significant decline in popularity over the years. Despite being one of the oldest and most widely used languages in the past, Fortran has failed to keep up with the times, and its usage has dwindled. But why has this happened? What factors have contributed to Fortran’s decline?
The Rise And Fall Of Fortran
Fortran, short for “FORMula TRANslating system,” was first developed in the 1950s by IBM. It was designed specifically for scientific and engineering applications, making it an instant hit among researchers and scientists. Fortran’s popularity soared in the 1960s and 1970s, with it becoming the language of choice for many government agencies, universities, and research institutions. Its widespread adoption was largely due to its ability to handle complex mathematical calculations, making it an ideal language for numerical computations.
However, as the years went by, Fortran’s popularity began to wane. The language, once hailed as a revolutionary tool, started to show its age. Newer languages like C, C++, and Java emerged, offering more modern features, flexibility, and ease of use. Fortran’s rigid syntax, lack of object-oriented programming (OOP) support, and limited graphical capabilities made it less attractive to developers.
The Main Reasons Behind Fortran’s Decline
So, what are the primary reasons behind Fortran’s decline?
Complexity And Steep Learning Curve
One of the major obstacles to Fortran’s adoption is its complexity. The language has a steeper learning curve compared to modern languages, making it challenging for new programmers to grasp. Fortran’s syntax, although elegant in its own right, can be overwhelming, especially for those without a strong background in mathematics and computer science. The language’s focus on numerical computations means that it is not as forgiving as other languages, and even minor errors can lead to catastrophic consequences.
Lack Of Modern Features And Updates
Fortran has not kept pace with modern programming trends. Its syntax and structure have remained largely unchanged since its inception, making it seem outdated compared to newer languages. The language lacks many modern features, such as garbage collection, exception handling, and support for OOP. While later versions of Fortran, such as Fortran 90 and Fortran 2003, have introduced some modern features, they have not been enough to stem the tide of Fortran’s decline.
Limited Graphical Capabilities
Fortran’s primary focus on numerical computations means that it is not well-suited for graphical applications. While it is possible to create graphics in Fortran using external libraries, the language itself does not have built-in support for graphics. This limitation has made it less appealing to developers who need to create graphical user interfaces (GUIs) or interactive applications.
Limited Portability And Compatibility Issues
Fortran’s lack of portability has also hindered its adoption. The language is heavily dependent on specific compilers and platforms, making it difficult to port Fortran code between different systems. This has led to compatibility issues and has limited the language’s ability to be used in diverse environments.
Competition From Newer Languages
Lastly, Fortran faces stiff competition from newer languages that have emerged over the years. Languages like Python, MATLAB, and R have become popular in the scientific and engineering communities, offering more flexibility, ease of use, and modern features. These languages have become the preferred choice for many developers, further contributing to Fortran’s decline.
The Legacy Of Fortran

Fortran’s unique strengths in numerical computations make it an attractive choice for emerging fields like machine learning and artificial intelligence. Researchers are exploring ways to use Fortran’s performance capabilities to accelerate machine learning algorithms, potentially reviving interest in the language.
Conclusion
Fortran’s decline is a cautionary tale of how even the most popular languages can fall out of favor if they fail to adapt to changing times. While Fortran’s popularity may never reach the heights it once achieved, its legacy continues to be felt, and efforts to modernize the language are underway. As the programming landscape continues to evolve, it will be interesting to see if Fortran can regain its former glory or remain a relic of the past.

What Is Fortran, And Where Did It Come From?
Fortran, short for “FORmula TRANslating system,” is a programming language developed in the 1950s by a team of developers at IBM, led by John Backus. It was designed to solve complex mathematical problems and was initially used for scientific and engineering applications. The first version of Fortran, known as Fortran I, was released in 1957 and quickly gained popularity among researchers and scientists.
Fortran’s early success can be attributed to its ability to simplify complex calculations and its speed, which was much faster than other programming languages of the time. As the language evolved, new versions were released, including Fortran II, III, and IV, each with new features and improvements. Fortran’s popularity continued to grow, and it became the de facto standard for scientific computing in the 1960s and 1970s.
What Are Some Of The Key Features Of Fortran?
Fortran is known for its concise and expressive syntax, which makes it well-suited for mathematical and scientific applications. It is a procedural language, meaning that it follows a step-by-step approach to solving problems. Fortran is also a compiled language, which means that the code is translated into machine code before it is executed, making it very fast. Additionally, Fortran has built-in support for arrays and matrices, making it an ideal choice for numerical computations.
Fortran’s strengths also include its ability to handle complex numerical computations, its support for parallel processing, and its compatibility with a wide range of platforms. However, Fortran’s syntax can be confusing for beginners, and its error messages can be obscure, making it challenging to debug.
