The Future of the Cloud is WebAssembly
summary
Claim: WebAssembly plus WASI will power server workloads, not just browsers. Uses the open source Spin CLI and Firon cloud to build a Rust HTTP function, compile to a .wasm ~2 MB binary, and deploy it to production in under 66 seconds. Benchmarks show Docker images shrinking from ~23 MB to ~550 KB and cold starts dropping from ~250 ms to ~50 ms. Demo runs a Rust + TypeScript key/value app using the new component model, proving multi-language modules interoperate securely and quickly.
