Genuinely curious, not being sarcastic or cute here. With hype everywhere, and job ads filled with buzzwords and acronyms, how does one choose what to learn? Something that is sane, that is joyful to work with, that will be around for at least a few years, but also puts food on the table? I suppose SQL is going to be around for a while? Any other recommendations?
If you're in IT operations I guess it's harder to keep up, because everything is different.
