I think I've seen you comment this on every recent WASM post, and I'm really wondering what you think breakthrough success looks like for a low-level technology like WASM?

Do you expect everyone to hand-code their websites in WASM? Do you expect every webapp be cross-compiled to WASM?

From where I'm standing, WASM is extremely successful in its specific niches: in enabling islands of high-performance in otherwise web-based software, and in sandboxing plugins to native apps/servers.
