Embedding WASM in the Future

on YouTube ↗34m

" summary

Argues that WebAssembly already runs at scale in embedded devices (Amazon Prime Video, Disney Plus) and can shrink complex control algorithms to tens of kilobytes (utility grid demo under 100KB). Describes RLBox-style micro‑isolation, compares wasm runtimes (Wasm3, Wasmtime, WAMR) and finds WAMR with AOT best for deterministic control, flags sandboxing vs. call‑overhead tradeoffs and hardware aids like CHERI/Cherry capability memory to regain performance, and stresses tooling, WASI interfaces, orchestration and 30‑year versioning needs.
