With the instant gratification generation, not having dynamic content is going to be a tough sell. I will however agree, there is a gross overuse of it.
The funny part about your reply is JS-heavy websites delay instant gratification on slow connections or machines. They can take 10-30 seconds then objects start jumping around as you try to click them.
Whereas a cached static page or templated dynamic loads pretty instantly if it's mostly text content. In a way they understand if it's graphics.
