I'd recommend learning how to learn. Making learning and curiosity a part of your every day existence will have more of an impact that the latest hot language or framework.
I am compelled to agree with you, inasmuch as the irony of "what is the newest thing to learn" wouldn't be much of a hipster position if it weren't borne on the fact that must learn new things, always. Always. Since the beginning of social computing - when we've all had access to the same degree of technology - our languages, tools, and frameworks have always been changing. It is one reason for the existence of an ivory tower - sometimes you need to wizard-out, just to get peace from the noise. Trouble is, you inevitably end up casting new spells. There is no such thing as 'a brand new thing' to learn, alas the truly hipster edge can't be learned yet. ;)
