KEYNOTE: WebAssembly Update: The Proposals, Wasi, And The Component Model
summary
The update lays out concrete deliverables: WASI 0.2 and the component model that let binary modules declare capabilities, be composed, and run under runtimes like wasmtime/wasmer. Demonstrations recompile jq and TensorFlow backends to Wasm; a JS CPU path that takes 3.3s drops to 49ms on integrated graphics and to 5ms on a beefy GPU. A pipeline (OpenCV → TensorFlow → Rust Sudoku solver) runs live in the browser. Tooling includes wit IDL, wit-bindgen, a cargo component plugin, jco, and HTTP/CLI "worlds"; 0.3 adds async futures/streams.
