I think the IE9, Firefox, V8 and Squirrelfish Extreme JS engines are all "fast enough". When you start performing that quickly, JS is no longer the bottleneck. The graphs the MSDN blog post has seem to demonstrate this nicely. Amdahl's Law and all that.

While JavaScript is getting faster and faster, I still don't think that JavaScript (especially DOM operations) implementations are "fast enough" yet, not even on Google Chrome. I still have to jump though hoops to get complex javascript/ajax heavy sites (approximating the richness of native apps) working reasonable quickly. There was a lot of advancement lately, but I think there's still a lot of space for improvement.

I don't think SunSpider tests DOM operations. I admit I was thinking purely of the JS engine and not of the DOM, and that the DOM is still a bottleneck. (I'd much rather the IE folks focus on DOM stuff rather than try to get raw JS any faster than they have already.)
