The Return of Write Once, Run Anywhere
summary
History and current state focus on concrete outcomes: a global programmable CDN running WebAssembly modules compiled ahead of time and shipped to thousands of servers, achieving hundreds of gigabits per second and hundreds of thousands of requests per second; compiler and runtime work that produced Cranelift and Wasmtime (and the earlier Lucet experiments) to make AOT and JIT feasible; standardized interfaces via WASI and the Component Model with interface types so multiple languages interoperate in a sandboxed, performant way.
