Kubernetes very easy to use, worth learning imho. One hour's worth effort yields great advantage for work.
Vim not worth learning to use as adult. Time too valuable. Takes too long to become extension of body. Best learned as child/teenager. Time worthless then. Maybe if you can learn it fast. Took me years of teenage to get unthinking proficiency.
I disagree, I learned Vim in my 40's after decades on emacs. For a month it was awful, but I have since recouped the time lost many times over. Other developers on my team went through the same.
I also disagree. I learnt vim in my 50's and am using it daily now. In fact, I find that I use jk (which I've muscle-memoried to 'ESC' in nearly every application). Sometimes it doesn't work :-). But it did when I went on to learn org-mode during Covid-19 by parachuting with doom-emacs. There is no need to avoid learning the good stuff.
