I think your criticism is of a matter so small that it can barely be seen. Some self-developmental things to learn that will almost never be obsolete in one year (or ten years:) - Patterns and ideas in languages that you haven't been exposed to before (e.g. continuations, or pattern matching, or actors, or dependent types, or STM, or...) - All about time-tested tools and protocols or software or media or files or hardware that you work with or on, of which there is no shortage. - Interesting data structures and algorithms, and related math. It all feeds into fundamental problem-solving, you can work in a way such that you are learning it as you go along, and it's more than a lifetime's worth.
