I don't think the x86 instruction set is particularly strongly typed. Strong typing is a property of the compiler, so I don't think this rules Javascript out of being the 'machine code'. To do a Roger, I think the conclusion is that Javascript needs better support for processing binary data, although a PNG download based hack provides much of what is required.
