Why Learn Prolog in 2021?
How do you guys think about the opportunity cost of learning  dead/dying/new/unpopular languages? Even with newer languages that are gaining popularity and are likely to be used in the future, I struggle to justify the time investment. I could be wrong but some of my concerns are:- my time is better spent getting deeper into some more popular language that I already know to some extent- unused skills deteriorate with time so by adding a new language that you don't need professionally right now, you also need to add the future time and effort of practicing and maintaining that skill- I could be wrong but I feel that it's a red flag to have too many of the more esoteric languages on your resume.I do enjoy tinkering with a new language but very often it just feels like a distraction.Thoughts?
