>but it is easy to become irrelevant if you have no breadth and a disruption occurs.

Disruption does not occur that quickly that proven-capable humans suddenly become utterly useless. If a major tech company with a good reputation starts blogging about it, maybe read a few articles on it and see if it's interesting enough to spend some time on.

There's a neat bias in development where a disruption implies that people above the developers will 100% use the new disruption tech perfectly, and somehow, only developers are the ones at risk of being left behind. Change usually goes much slower, and usually there is an experimental phase before suddenly betting your entire production infrastructure on new X technology. You can also safely bet there will be tutorials and videos to quickly bring you up to speed if the technology is that disruptive.

Also, you have to remember that technologies come quickly but they can also leave quickly as well, making your time spent quickly adjusting to them worthless. Ask Silverlight developers.
