4 Programming languages that might get obsolete in 2023 

Erlang 

Erlang supported banking, e-commerce, computer systems development, and instant messaging services. Due to its complex debugging procedures and critical deployment issues, it has yet to be in use in recent days. 

Scala 

Scala performance was not the issue. However, most developers needed to be aware of Scala's features. Thereby adding it to the list of dying programming languages 

Cobol 

The early primary frame programming for business transactions, banking, and many more was handled by *COBOL*. It had a tougher verbose syntax with slow compilation and deployment. 

Fortran 

Fortran is on the list of dying programming languages because developers soon had to migrate to other languages due to a lack of dynamic memory, reliability, and unsafe code prone to cyber threats.
