Clouded, this boy's future is.
Better learn several different technologies to avoid
Vendor Lock-in. Read about it:

Development of any all world-wide technologies is not rational, is a result of struggle of multiple wills, interests and ambitions and is not predictable. I personally reckon that WWW is in a very well prolonged dead-end, due to fatal limitations of HTTP originally designed for pure client-server and nearly static content,

Conclusion: instead of sticking just to a single technology, do something directly opposite: get yourself ready for new twists and turns.
