I'd say stop worrying about the technology you use and start worrying about the question you're trying to answer and problems you're trying to solve.

> Programmers should really take a leaf from the Mathematics & Sciences. In those subjects they are endlessly looking for new solutions and then crediting or discrediting each other, in a logical manner with the use of facts, calculations, proofs and actual data. Not gut feelings, random beliefs and twitter debates!

This problem is worse in the sciences, there are even more 'schools of thought' and people stuck in certain modes of thinking. "Science advances one funeral at a time" is a well-known quote for a reason.

That all said, yes, go explore new technology, try it out, do what you enjoy, I find it's only ever been beneficial :)
