As I see it, choose boring tech where stability is paramount, i.e. at work. Opt for fancy new stuff when you want to learn, i.e. at home. The first will let you honor your moral contract of service quality with your clients. The latter will enable you to grow and experiment in a low-stakes environment. Also, when the new toys become boring, you'll be The Guru (tm) everyone goes to for advice. You're happy, and everyone wins. Edit: of course 'work' and 'home' are used loosely here, not taking into account real-world diversity.
