Geoffrey Huntle Is Cursed: Making a GenZ slang programming language with Claude (simonwillison.net)

Geoffrey Huntley has leveraged the AI Claude to create an entirely new programming language called "cursed," featuring Gen Z slang as its lexical keywords. Developed over three months through iterative prompting, this language flips traditional syntax on its head with playful terms like "vibe," "yeet," and "slay," offering a fresh and humorous take on programming language design. The project showcases not only creativity but also the practical ability of AI to drive complex software engineering, as "cursed" includes both an interpreter and a compiler capable of producing native binaries for macOS, Linux, and Windows via LLVM. Technically impressive, "cursed" evolved through three implementations—in C, Rust, and Zig—demonstrating Claude’s versatility in code generation and language porting. The entire project reached nearly 1,200 commits, mostly generated using Claude through Sourcegraph’s Amp, which also automated detailed commit messages. Geoffrey estimates the cost of building such a multi-edition compiler at around $14,000 USD. This experiment not only exemplifies AI-assisted software development at a significant scale but also highlights the emerging potential of large language models to collaborate creatively on sophisticated coding tasks, pushing the boundaries of how we conceive and build programming tools.
