Re: I will not use this
"It's basically the same as the Javascript (ECMAScript) permissions - given that WebAssembly has its roots in the "virtual machine" made in Javascript."
Yes, and I already don't allow almost any Javascript to execute in my browser.
"Seriously, the problem is not what technology you choose, but how stupid your browser manufacturer's are."
No, the problem is that websites cannot be trusted to execute code on my machine.
"You've had a webassembly-enabled browser for several years now, I guarantee it."
My browser allows me to disable it, which I do.
"Focus on the problem (browsers which don't implement proper security for their page interpretation) not the brand name on the language that exposes that (e.g. Javascript, WebAssembly)."
My problem is not improper implementations by browsers -- that's something that can be addressed. My problem is that even if the browser's security is 100% bulletproof, client-side scripting is still for more powerful and capable than I'm comfortable allowing web developers to use on my machines.
