It is difficult to predict with certainty which programming languages will disappear in the next 10 years. However, some languages that may be at risk of becoming obsolete are those that are not widely used or have limited application.

One language that may be on the decline is COBOL. This language was developed in the 1950s and is primarily used for business and financial applications. However, with the advancement of newer languages such as Java and C#, COBOL has become less popular. Many companies that still rely on COBOL systems are also beginning to phase out the language in favor of more modern alternatives.

Another language that may be on the decline is Pascal. This language was developed in the 1970s and is often used for educational purposes. However, with the rise of more modern languages such as Python, Pascal has become less popular. Additionally, many universities have also begun to phase out Pascal in favor of more modern languages in their computer science curriculums.

Fortran, a language primarily used in scientific, engineering and numerical computing, also could be on the decline, with the widespread adoption of R, Python and Julia, which are now being used more and more in these areas.

Additionally, some experts believe that within a decade, many programming languages will converge into fewer languages, as the industry shifts towards low-code and no-code platforms that enable non-technical users to create software without having to write code.

While it's hard to predict which language will disappear in the next 10 years, it's important to note that the programming landscape is constantly evolving. A language that may not be popular today could become widely used in the future, and vice versa. As a developer, it's important to stay informed about the latest trends and technologies in order to make informed decisions about which languages to use and which to avoid.

Overall, it's important to note that while a programming language may not be in as much demand as it once was, that doesn't mean it's useless. There are still a lot of systems and software that rely on older languages, and it's not always easy or cost-effective to completely rewrite them in a new language. Therefore, even if a language is on the decline, it may still have value for certain niche applications or industries.

In conclusion, it is hard to predict with certainty which programming languages will disappear in the next 10 years, However, languages like COBOL, Pascal, and Fortran may be at risk of becoming obsolete due to the advancement of newer languages and the shift towards low-code and no-code platforms. But as the programming landscape is constantly evolving, it's important for developers to stay informed about the latest trends and technologies in order to make informed decisions about which languages to use and which to avoid.
