V8, JVM, CLR and others are well proven runtimes providing a well functioning sandbox, but of course we test a lot. I am sure you know what the risks are with native code - you're a native code proponent after all; any code running in a medium and bigger company that could misplace money is a huge liability. I don't know what magic you're talking about - we're simply waiting for WASM to standardize GC, SIMD, tail calls etc, you can read more here[0]; and to get the execution optimized like V8 did over the past 10 years[1] (WASM on V8 gets most of these gains by default as a bonus). I already said why I want WASM: because it provides a good sandbox and opens most ecosystems through safe and typed interop. I don't care about ES modules in particular - I care about ES modules, Ruby modules, Python modules, Prolog modules, Fortran modules, C modules, Rust modules, AssemblyScript modules, COBOL modules, Erlang modules, F# modules, Java modules, and so on - at once. Finally a future where I can use and trust any library and not get limited to the language I use (if I don't want to spend most of my time fighting and securing C ABI interop, if at all humanly possible) is there.
