I think the point is you shouldn't need JavaScript in a web browser in the first place.
JavaScript was created when HTML was primitive, as a means of extending a web sites capabilities, and usability etc.
You 'should' now be able to do everything in HTML/CSS, and that includes anything dynamic. If there is something that you can't do in HTML/CSS currently, that needs JavaScript, then HTML/CSS should be extended to add that functionality, assuming it's valid of course.
I'd love to see a time when all the wiizzy stuff can be done without needing to revert to JavaScript, at that point JavaScript could be deprecated, and not just disabled in web browers, but actually removed from the code completely.
AC as I work in a dev area that heavily uses JavaScript, and they know me on here :-)
