I think when someone says "production ready AOT" in any context, it's never quite obvious what they mean. As ckok implied, even when AOT is "working" it may generate a 100mb executable. For some end users that is production ready (like Facebook, who reportedly were shipping 1gb+ AOT'd php executables to their server cluster) and for other end users it is not (because a 100mb browser app is a closed tab.) WASM now and emscripten before it both were designed and optimized for POSIX C apps and for games, and they're pretty good for those scenarios. Larger-scale stuff is pretty tricky and the tooling ecosystem will have to continue to grow to support more real-world applications. JIT, stackwalking, GC, etc are all still not there on WASM - thankfully threading is finally crossing the finish line but even that has taken years.
