Rust, WebAssembly, and the future of Serverless
summary
Claims that WebAssembly plus wasm extensions could have replaced Docker in 2008 and that WebAssembly on the edge is practical get concrete backing: Rust toolchain (wasm-bindgen / wasm-pack), the Lucet runtime, and Cloudflare Workers / Fastly Terrarium are shipping; DOSBox and Unreal Engine compile to wasm; a simple Fibonacci drops from 185 bytes to 62 bytes in wasm vs asm js; Microsoft data shows ~70% of security bugs are memory‑safety related, motivating Rust+wasm for smaller, safer serverless edge deployments.
