In my opinion as someone who works in the field, including interviewing and screening candidates, yes and no.<p>Yes in the sense that I don't think the field, such as it is, will expand sufficiently to accomodate everyone.<p>But no in the sense that I think the sorts of skills and problem solving approaches that one acquires while training for data science will become important in other fields.<p>So in my opinion even if everyone studying machine learning and statistics etc. doesn't get a data scientist job title, there are going to be increasing numbers of ways to apply that knowledge to existing jobs.
