Carbon is designed as an incremental successor to C++ to address its technical debt, lack of memory safety, slow compile times, and dysfunctional evolution process. Key highlights include: working bidirectional C++/Carbon interop (calling C++ from Carbon and deriving C++ classes from Carbon base classes), inline C++ code blocks within Carbon files, and a detailed memory safety design featuring strict and permissive modes. The memory safety model uses 'places' and 'place sets' to track pointer provenance and detect use-after-free at compile time, plus thread safety analysis inspired by Clang's W-thread-safety. The talk outlines a multi-step migration path from C++ to permissive Carbon to strict Carbon. Carbon is approaching a 0.1 release targeting evaluation, with early internal Google pilots underway. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does Carbon have working C++ interop yet? Yes, bidirectional C++ interop is now functional in Carbon, four years after the project's announcement. Carbon code can import C++ headers or C++20 modules through a special CPP package, call C++ functions and templates using real Clang overload resolution, and C++ code can also derive from and call Carbon classes directly, demonstrated live in Compiler Explorer. _Track how Carbon's C++ interop matures before betting a migration strategy on it, via daily.dev._ ### How does Carbon plan to achieve memory safety without rewriting all existing C++ code in Rust? Carbon introduces a strict mode (fully memory safe, comparable to Rust) and a permissive mode (an intermediate step stricter than C++ but with relaxed compile-time rules) so codebases can migrate incrementally. It uses a place-based type system to track pointer provenance and invalidation, similar in spirit to Rust lifetimes, letting developers add safety annotations gradually without a full rewrite. _Developers weighing incremental memory-safety migrations can follow Carbon's design evolution on daily.dev._ ### When will Carbon reach a usable 0.1 release for evaluation? Carbon aims to reach version 0.1, marking a shift from experimental research to formal evaluation, possibly early in the following year, though no firm commitment was given. Requirements include a working compiler and toolchain supporting modern Clang-compatible C++, functioning build system integration, mature C++ interop, and an initial memory safety design, all still in progress at the time of the talk. _Anyone evaluating Carbon for a C++ migration path can follow its 0.1 roadmap updates on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@heath34** · 0 upvotes > Where can I watch this? ## Similar posts on daily.dev - [Why CPP is going to be relevant AGAIN?](https://daily.dev/posts/why-cpp-is-going-to-be-relevant-again--p1o0tcdzt) · Medium · 43 upvotes · 4 comments - [C\+\+26: Reflection, Memory Safety, Contracts, and a New Async Model](https://daily.dev/posts/c-26-reflection-memory-safety-contracts-and-a-new-async-model-qkor2ctht) · InfoQ · 18 upvotes · 2 comments - [C3](https://daily.dev/posts/c3-5w6a8vyad) · Hacker News · 0 upvotes · 0 comments - [C\+\+26 is done\! — Trip report: March 2026 ISO C\+\+ standards meeting \(London Croydon, UK\)](https://daily.dev/posts/c-26-is-done-trip-report-march-2026-iso-c-standards-meeting-london-croydon-uk--qgbxvzmu3) · Sutter's Mill · 18 upvotes · 1 comments --- Tags: [#c++](https://daily.dev/tags/c++) [View this post on daily.dev](https://daily.dev/posts/carbon-graduating-from-the-experiment---chandler-carruth---ndc-toronto-2026-tcuzreutd) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Carbon: graduating from the experiment - Chandler Carruth - NDC Toronto 2026","url":"https://daily.dev/posts/carbon-graduating-from-the-experiment---chandler-carruth---ndc-toronto-2026-tcuzreutd","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/carbon-graduating-from-the-experiment---chandler-carruth---ndc-toronto-2026-tcuzreutd"},"datePublished":"2026-07-20T12:19:13.741Z","dateModified":"2026-09-14T08:53:44.468Z","description":"Chandler Carruth gives a four-year progress update on the Carbon programming language at NDC Toronto 2026.
