There's a difference between jumping on the hype train and being stubbornly stagnant. You will definitely be left behind if you refuse to adapt to new "industry standard" tech, even if all of that new tech is 90% old concepts with slight changes, repackaged. That's not to say you should jump on every new half-baked hackathon-originating javascript framework. But it does mean you should have your finger on the general area of the pulse of where the industry is moving, and start learning that tech. For example, pick up Rust for systems programming, instead of C. I know a web developer who refuses to learn or use any web tech besides PHP. Finds cloud-based hosting confusing as well. "I can do anything I need in PHP." Everything, except find good paying job that isn't maintaining gnarly legacy codebases. Doing PHP is his bread and butter, and unless he decides to learn some of the newer (stable) webdev tech, he's going to find himself with no marketable skills in the future.
