Meanwhile not having programming languages is a disaster as I explained in my parent comment but did your brain process the added value that such a change would bring to the world?
"One just needs to fully sandbox the VM" this is easier said than done. I explained in another post why Apparmor/Selinux are not nearly as effective as the Chrome sandbox. As for V8, sure, you could port over many mitigations it has to graalVM and get it running in a similar sandbox. Feel free, I'd certainly support you doing so.
Sure, my brain processes the benefit of other languages just fine. I'm excited to see wasm come to the browser.
I'm excited to see wasm come to the browser. Yeh but it doesn't have native binding with the browser APIs nor does it have multilanguage interoperability, hence the added values of graalvm over wasm.
