I also agree that they would not - but I guess everyone has different perspectives. I think the major thing here is that if you work in the field, you can regonize that a lot of job titles could be avoided - eventually what is the important aspect is the skillset, and skillset pretty much overlaps with each other. As an example, Data Scientist will eventually just be Data Analysts if they don't keep up with latest system architectural desgins - if they focus on just one thing they will eventually be pushed out of the market and the market will be re-invented. At the end of the day we are all engineers focuing on different areas.
