We are doing R questions once a week as they seem to be popular and they help me learn as well 😉
R and Python, really the Data Science and Machine Learning, interest is expanding because there is lots of publishing and writing about how companies are starting to use these technologies more. Whether this is useful and they will continue remains to be seen, but if you have an interest, learn them. Learning is good and keeps your brain fresh. It's a skill that you need.
I agree with Jeff that becoming better at SQL is important. Much of the ML/AI stuff still involves moving data around, cleaning it, etc., and SQL does a great job of that, but if you want variety, and your company uses other languages, splitting your learning is fine.
There is no should. You must decide what you are interested in and what presents opportunities for you
