I continue to be baffled by this sort of "novelty-chasing" --- do I really care about "interesting new places" or "interesting new ideas"? No; and in fact I'd rather not, because it takes time and energy away from actually solving useful practical problems, besides the ones you create yourself in chasing after the latest cruft.
PHP is slow on an absolute scale, but chances are that a minimal, straightforward application written with it can perform better than something with a bloated framework on top in a different language. That takes true skill and experience, not something you can get if you're continuously jumping around trying to chase the fashion trends.
As someone who has witnessed several major trends in programming come and fall, the amount of churn (and encouragement thereof) in the web community is astoundingly unsettling.
