Programming languages: It's time to stop using C and C++ for new projects, says Microsoft Azure CTO

Mark Russinovich, the chief technology officer of Microsoft Azure, says developers should avoid using C or C++ programming languages in new projects and instead use Rust because of security and reliability concerns.

Rust, which hit version 1.0 in 2020 and was born at Mozilla, is now being used within the Android Open Source Project (AOSP), at Meta, at Amazon Web Services, at Microsoft for parts of Windows and Azure, in the Linux kernel, and in many other places.

Engineers value its "memory safety guarantees," which reduce the need to manually manage a program's memory and, in turn, cut the risk of memory-related security flaws burdening big projects written in "memory unsafe" C or C++, which includes Chrome, Android, the Linux kernel, and Windows. 

Microsoft drove home this point in 2019 after revealing 70% of its patches in the past 12 years were fixes for memory safety bugs due largely to Windows being written mostly in C and C++. Google's Chrome team weighed in with its own findings in 2020, revealing that 70% of all serious security bugs in the Chrome codebase were memory management and safety bugs. It's written mostly in C++.
