Rust is a systems programming language that has topped the Stack Overflow Developer Survey’s “most loved language” category every year since 2016. In 2025 it has moved beyond niche systems work to be used in web backends, command-line tools, embedded systems, and increasingly in the Linux kernel and Android codebase. Is it worth learning?
What Rust Does Differently
Rust enforces memory safety at compile time — without a garbage collector. Its ownership system (each value has exactly one owner; when the owner goes out of scope, the value is dropped) prevents entire categories of bugs: use-after-free, dangling pointers, data races in concurrent code. These are the bugs that cause most security vulnerabilities in C and C++ code. The compiler’s error messages are famously helpful — they explain the problem and suggest the fix.
The Learning Curve
Rust’s learning curve is the steepest of any mainstream language. The borrow checker (the compiler component that enforces memory safety) fights you constantly in the first weeks. Many experienced programmers find Rust frustrating for the first month, then reach a point where the compiler’s guarantees feel like a safety net rather than a constraint. Expect 2–3 months to reach productive competence from a strong programming background.
Where Rust Is Used
Command-line tools: ripgrep, fd, bat, eza (all widely used, all Rust). Web backends: Axum, Actix-web are competitive with Go for performance and better for type safety. WebAssembly: Rust compiles to WASM efficiently and is the language of choice for performance-critical browser code. Firefox: Mozilla wrote Rust to improve Firefox’s rendering engine. Linux kernel: Rust is now accepted as a second language for kernel modules.
Should You Learn It?
Yes, if: you are a systems programmer tired of memory bugs, you want to write high-performance web services, or you are interested in embedded/IoT work. Less urgent if: you do primarily web frontend work (TypeScript is more relevant), data science (Python dominates), or business applications (Go or Kotlin are faster to productive). Rust knowledge is increasingly valued and will continue to be — the investment is not wasted.
