The Big Idea#
As AI abstractions upend our relationship with code, engineering craft is bifurcating: we must simultaneously grapple with emergent, functional behaviors in massive models while deliberately preserving the mechanical, systems-level intuition that historically grounded software ethics.

watgo - a WebAssembly Toolkit for Go · Eli Bendersky
This piece introduces watgo, a zero-dependency WebAssembly toolkit written in pure Go that parses, validates, encodes, and decodes WASM. The core of the system lowers WebAssembly Text (WAT) to a semantic intermediate representation called wasmir, flattening syntactic sugar to match WASM’s strict binary execution semantics. To guarantee correctness, watgo executes the official 200K-line WebAssembly specification test suite by converting .wast files to binary and running them against a Node.js harness. An earlier attempt to maintain a pure-Go execution pipeline using wazero was abandoned because the runtime lacked support for recent WASM garbage collection proposals. Engineers working on compilers, parsers, or WebAssembly infrastructure should read this for a masterclass in leveraging specification test suites to bootstrap confidence in new tooling.
