One could also argue that it's better to interpret "stay current" as being about "learn new frameworks", but rather "learn important concepts and their applications."
One can write object oriented code (with clear modules and interfaces) in plain-old-C (see "C Interfaces and Implementations"), just as one can write Fortran in Ruby (and I don't mean by creating a DSL sensitive to positions of characters in a line).
