I believe the parent comment was referring to hyperlinks, not dynamic linking.
The point was more that once webpages become applications running on the client (think single page apps), the natural document metaphor of web pages and the tooling built on it (hyperlinks, forward/back, bookmarks, history) falls apart unless you do extra work to ensure that experience is maintained.

But not everything needs to be a document. Sometimes the thing you're working with really is an application and not a document.
To me, one of the biggest problems with the current web is that we've commingled "app stuff" and "document stuff" so badly that browsers have been forced to become a shitty, inferior X-server (or Operating System outright), instead of being really good browsers. Browsers for browsing is great... browsers as a UI remoting protocol, is a bit janky.
