I've spoken about Relevance before in IT - specifically adapting to fundamental changes in the industry. Some guy (+Anban) mentioned that one of the changes he sees is being full stack - being not only able to take a requirement through the full development cycle of elicitation, design, and documentation (which nobody will read), but also through development and implementation as well. DevOps if you must.
So I think there is a need to change with the times, and learn how to do web development. These new frameworks from Google and Facebook, and perhaps training like this nanodegree can really help make that change and you keep relevant?
