Interesting question, I feel that if you are good in a particular area (Say php / css / js / html) then you will find each new component / framework actually simplifies your life or makes it easier. The trouble is if you are more of a heavy js developer and are typically labelled as a web developer. Then you feel like you have to know about SASS (css) / HTML5 video standard / Scala and everything else related to the web field!
I think that as web development grows and matures, it will finally have multiple experts who need to work together and with each expert having no problem in catching up or using the latest paradigm in their area.
I would recommend you specialize / try and learn whatever you are good at.
