AI-generated SIMD drop-ins for Go stdlib cover 21 repos, 6 architectures

Daniel Lemire shares go-simd, an AI-assisted project providing SIMD-accelerated drop-in replacements for Go standard library packages, claiming byte-identical compatibility. It covers 21 repositories including encoding/base64, encoding/json.Valid, strconv, etc., and supports six SIMD targets: amd64, arm64, riscv64, loong64, ppc64le, s390x. All hot loops are real SIMD assembly generated by go-asmgen, with no CGO required. Lemire notes it likely relies on data parallelism (SIMD) and invites testing feedback.
