I think one must know at least one programming language and be extremely good at it. Picking up other languages is then just getting used to it's syntax and understanding it's nitty-gritties. If you start with a very low level language like C++, it might be intimidating at first but if you start with python it would be a more friendlier language. But I think once you master C++ and data structures in C++, there is no language which will ever feel difficult to you. At the end of the day, programming language is just the start but an essential step in your development/research journey!
Prominent data researchers need proficiency in programming languages like Python or R for effective data manipulation and a firm grasp of data structures and algorithms for efficient data analysis.
