## Summary

Jason Turner, host of CPPCast and C++ Weekly, discusses modern C++ (C++11 through C++17) for embedded systems, arguing that the language's 'zero overhead abstractions' allow high-level code to compile to efficient assembly. He explains how features like lambdas, `std::array`, and `constexpr` enable compile-time computation and optimization, often using Matt Godbolt's Compiler Explorer to demonstrate that the compiler generates optimal code without dynamic allocation. Turner advises embedded developers to trust the compiler, avoid dynamic memory and exceptions, and learn C++17 to leverage these efficiencies while managing template bloat.
