As a web user, I'm not grateful. I don't think having more pixel-perfect control or slightly faster JavaScript makes the web any better. All websites look slightly better, but the client side dies a little bit every time. In the web circa '96, anyone could write a web spider or web browser, and everyone did. There was tremendous innovation both client-side and server-side. Client-side innovations included things like search engines and Google. With the hyper-AJAXed world, client-side innovation becomes impossible. I don't think this is a net win for the world.
