I hear you. As a 46 year old "senior technical lead", I have to be choosy about what new things I commit the time to delve into.

That said, sometimes the little things matter, but you have to trust your intuition about the big picture to determine which techniques may be important in the near future, as be willing to understand that some of these technologies really are largely equivalent in many ways.

If I can just get my juniors to stop writing N*100 line subroutines, ironically coupled with "kangaroo code" with too many useless abstraction/indirection layers, and learn enough about the functional style (even though working in Java -- AKA "Object COBOL") to write small routines with clearly defined inputs and outputs, I'll be a happier man at this point.
