A frustrated Mozilla developer, tired of elevator malfunctions caused by programming errors, created Rust to address the inherent issues in C and C++. These languages, developed in the 1970s and 1980s, dominate critical systems but suffer from memory management problems that lead to major security vulnerabilities. Examples include a Firefox flaw exploited by the FBI to dismantle a child abuse network on Tor, and a 2014 Ukrainian attack that siphoned passwords from Russian users. Browser vulnerabilities sell for $400,000 for Firefox, $1 million for Chrome, and $3-4 million for iOS on the black market. Rust solves these issues through ownership, borrowing, and a borrow checker that delegates memory management to the compiler, eliminating entire classes of bugs. The language also simplifies parallel programming, which is crucial for modern multicore processors. Today, Amazon Prime, AWS, Android (50% of new code), Linux, and Windows are rewriting critical portions in Rust. Google reports that Rust training is as fast as C++ or Python, with reduced mental load during code reviews.
