Explore C++'s critical evolution toward safety-first development in this comprehensive conference talk from CppCon 2025. Examine how C++, the backbone of high-performance software for over two decades, must adapt to modern software engineering priorities that increasingly emphasize safety alongside performance. Analyze the current state of C++ safety mechanisms across multiple dimensions including functional, language, memory, lifetime, and data-race safety considerations. Survey existing safety techniques currently available in the language, identify key limitations in the current approach, and discover potential solutions for addressing remaining security challenges. Learn about the comprehensive roadmap for achieving robust safety guarantees in C++26 and future versions while preserving the unparalleled performance capabilities that make C++ indispensable for expert developers. Understand how C++ can embrace safety-by-default principles to support a broader developer ecosystem without compromising the raw speed and flexibility that have made it the go-to language for large-scale software development across industries.
