I had to do a double-take there. Pessimistic? I'm fully supportive of this!

But realistically speaking, it's going to benefit content providers more than the average browser. I'm talking about magnitude of impact here. I did not that that is would not impact the average user, but the magnitude of the impact is nowhere near as much as the boon to Google.

And your metaphor makes absolutely no sense since apparently large swaths of Chrome users already have this in their hands today!
