I would like to note that I don't work on V8 full time anymore and all opinions that I express on twitter are mine alone and not those of employer, my current or former team.
I am writing a blog post that condenses my feeling towards asm.js into something tangible.
I also would like to add that it still excites me much to see JavaScript to become faster and faster and that I anticipate real world JavaScript written by human hands to become faster in the future and I don't think we need AOT compilation shortcuts for that.
