Who on earth would want the subjective experience of reading a page to subject him to executing untrusted code, potentially compromising his privacy and security? I'd love it if all browsers had an 'Enable code' button or somesuch which had to be manually clicked for every page which used JavaScript. And not remembered. That'd go a long way to ensuring that JavaScript were only used where necessary. (for that matter, books have managed to be quite remarkable for centuries, with absolutely no interactivity)
