Google engineers have launched experimental programming language called Carbon, aimed at addressing the longstanding challenges of C++ and offering a modern alternative for developers who rely heavily on it.

🤔 Why Carbon?

C++ has powered the world for decades, but its evolution has been… slow. Google engineer Chandler Carruth unveiled Carbon at the CPP North conference in Toronto, expressing frustration with the stagnation caused by C++'s bureaucratic standardization process. Important language changes can take years, which isn’t ideal for modern development needs.

Carbon aims to change that — while building on C++ rather than replacing it outright.

“If you’re happy with Rust, keep using it. But if you’re stuck with massive C++ codebases — Carbon is for you.” — Chandler Carruth

⚙️ Key Features of Carbon

  • Readable, modern syntax
  • Full interoperability with existing C++ code
  • Migration tools to help transition from C++ to Carbon
  • Better support for modern OSes, architectures, and dev environments
  • Built using LLVM and Clang infrastructure
  • Focus on safety (e.g., uninitialized state tracking) and API design

Here’s a quick comparison of a simple function in C++ vs Carbon:

// C++
int Add(int x, int y) {
  return x + y;
}
// Carbon
fn Add(x: i32, y: i32) -> i32 {
  return x + y;
}

🌐 Community-Driven from Day One

Although Carbon began as an internal Google project, it’s now fully open source and hosted on GitHub. Discussions and development are taking place in the open, with contributions welcome from the broader dev community via Discord and GitHub.

The long-term goal? Transfer governance to an independent software foundation and keep Google’s involvement below 50%.

Carbon is still in its early days, but it represents a promising new direction for those deeply invested in the C++ ecosystem. With community-first values, modern design, and compatibility with existing code, it might just become the evolution path C++ has been waiting for.
