I don't this Operational Research algorithms would end up with big data technologies and AI. Even in AI problems, OR algorithms can be use for optimizing the outputs.
Would argue that it will cause an evolution but not a cessation. You might be interested in the link/talk @ https://www.ted.com/talks/tricia_wang_the_human_insights_missing_from_big_data
If hammer is not dying, then traditional OR is still surviving. The core idea behind OR is more important for one to develop novel ideas, algorithms.
Traditional OR is not from data or big data, therefore, my short article "intelligence without data" (you can get at RG) is useful for understanding OR without data or big data.
The optimization behind OR is important for applying OR, because everyone like the optimal method, algorithm, solutions, and development direction, etc., This is similar to intelligent or smart ones.
