Again, I'm not an expert coder, by any means, but I think that at this current point in time, there is a great deal of demand for coders, exactly as you described. I think the question is whether, in the long run, there will still be, strictly speaking, coding that's required. For example, in the context of artificial intelligence and the applications that are possible, what coders will do in the future could change significantly, and the emphasis may be that you actually need capabilities and skills or competencies that are broader than just coding related to STEM.
