Web Assembly
summary
WebAssembly compiles C/C++, Rust, Go and more into a sandboxed binary that runs in browsers and servers, with streaming compilation that gives smaller downloads and 3x startup speed for some apps (Figma). Demos include jq in browser, a clang/LLVM toolchain compiling C++ to WASM in-browser, Unity and Google Earth ports, and a Sudoku app combining OpenCV, TensorFlow and a Rust solver that runs and returns solved boards. Runtime interfaces like WASI/Wasmtime/Wasmer control file and network permissions; Ethereum 2.0 VM and wapm packages already use it.
