Sure! As long as you understand the problems and theories that are important to the domain (let it be machine learning, artificial intelligence, parallel/distributed programming, combinatorial optimization or cryptography), the language is the easiest thing to learn. On the other hand, if I need some very specific optimization that only people that know C++ intimately know, then such knowledge would not help me. On the other hand, I may only contract such specialists, depending on how often their specialty will be needed.
