It's resumé-driven development, and it's also entertainment-driven development. Bringing in new technologies gives you a chance to play with a new toy. That's an effective way to make your job more interesting when the thing you're supposed to be working on is boring. Which, in business applications, is more often than not the case.
In today’s job market resume driven development is a very rational choice. I work in medical devices so we are pretty conservative and generally way behind the cutting edge. This makes it really hard to find jobs at non medical companies. I would recommend anybody who has the chance to use the latest and shiniest stuff to do so because it’s good for your career .
Very good point. Seems like yet another example of how carefully optimizing all the individual parts of a system can paradoxically de-optimize the overall system.
