This statement is itself hyperbolic.
A lot of these advances are going to impact web applications. Sure if you're building a brochure site then you should probably stick to web technology circa 2000.
The article mentions 350MM chrome users, FF has about the same market share. That makes close of 3/4 of a billion web users who will automatically receive the updates that allow app developers to target these new features. That's a lot of potential customers.
Oh and for those who can't or don't know how to upgrade away from IE7-10 there's ChromeFrame. That covers the remaining portion of the web.
In other words... no, the article is not hyperbolic and feel free to take all of it seriously.
