Greg KH, a Linux kernel maintainer, strongly advocates for incorporating Rust into the kernel, citing how it eliminates common C-related bugs and memory safety issues. He emphasizes that Rust would particularly benefit new code and drivers, while acknowledging the ongoing importance of improving the existing C codebase. The discussion addresses concerns about mixed-language maintenance and developer adaptation.
Carbon is Google's experimental open-source project aimed at developing tooling for automated migration of C++ code to a modern programming language with improved governance. The project emerges from Google's disagreements with the C++ Standard Committee and focuses on solving C++'s evolution challenges while maintaining interoperability with existing codebases. Unlike other successor languages, Carbon prioritizes automated code migration and fundamental language rework while building stronger abstractions.
