I have never minded using a so-called niche language. Since 1982 I have been very fortunate enough to be paid a good fraction of my time for using Common Lisp - I consider this to be largely good luck and I am grateful for how things turned out. I also like Scheme but literally no one has ever paid me for Scheme development. In the USA, we have a saying that “you dance with the person you go to the party with.” My dance partner has been Common Lisp. I still feel like I am still a student. I started to read Let Over Lambda (a reference to closures) a few months ago which has reinforced my realization that there is so much about a programming language that I have used for 38 years that I still want to explore. All that said, I have often totally enjoyed building systems with C/C++, Java, Python, Prolog, etc. Designing and writing code can be fun in any language.
