The examples are mostly about the military. It's hard to extrapolate that to IT. If anything IT is becoming more specialized because our tool stacks are becoming more complex. For example, pre-web, UI's were generally easy to create and change due to their WYSIWYG nature. The Web pissed on WYSIWYG big-time because it's "flow-based", and different browsers, versions, and OS settings would render differently. Thus, it generally requires a UI specialist to do it well. It might change with a new tool or standard, though. The pendulum of approaches often swings back and forth over time, similar to how the industry swings between server-centric and client-centric designs. And, data-centric versus code-centric, etc.
