Google’s Lars Bergstrom told Rust Nation UK that migrating services from Go and C++ to Rust has yielded no productivity loss versus Go and more than 2x less effort than C++, with reduced memory usage and defect rates; he framed memory safety as a national security concern amid growing government and industry advocacy for memory-safe languages, while acknowledging pushback from C++ proponents and noting internal surveys showing high developer confidence in Rust code correctness.
