ppk's argument boils down to progress outpacing need. Businesses desire the bleeding edge in their online-facing products and if you want to be attractive as talent you need to keep up with the latest development trends.

The latest and greatest is hip but might not be entirely necessary. This is where we need to focus our attention and strike a balance.
