The History of Programming Languages: From Fortran, Lisp, and ALGOL to Python, Rust, and AI Code Generation

The History of Programming Languages examines how languages shaped the way computational ideas became expressible, executable, teachable, maintainable, and institutionally useful. This article introduces programming-language history, machine code, assembly language, automatic coding, Fortran, Lisp, ALGOL, COBOL, BASIC, Pascal, C, Simula, Smalltalk, Prolog, ML, SQL, C++, Java, JavaScript, Python, R, Haskell, Rust, Julia, TypeScript, compilers, interpreters, runtimes, virtual machines, type systems, object-oriented programming, functional programming, logic programming, scripting, database languages, package ecosystems, language standards, software governance, AI code generation, and responsible computational reasoning.
