My answer to the question about the best language on Quora [1]. If you continue reading from here, please stick with me to the end. Ready to read to the end? Enjoy the ride!
My current answer is: Scheme [2] ☺ It gives me a large degree of freedom to explore ways to program which were much harder hard to explore in Python, C++ and Java. That’s why I’m currently switching from Python to Scheme.1
But depending on my current step on the road to improve my skills2 and the development group and project, that answer might have been any other language — C, C++, Java, Python, Fortran, R, Ruby, Haskell, Go, Rust, Clojure, ….
Therefore this answer is as subjective as most other answers, because we have no context on your personal situation nor on the people with whom you’ll work and from whom you can learn or the requirements of the next project you want to tackle.
Put another way:
The only correct answer is “it depends”.
The other answers in this thread [3] should help you find the right answer for you.
