Every discipline (academic, artistic, practical, even athletic) deal with certain types of problems and have develop their own heuristics for dealing with those problems. And because most discipline involve not a single skill but a set of skills, some disciplines will have skill overlap.
If you play music, run your own business, study (or practice) engineering, or become involved in an academic discipline you develop a set of skills you can carry to other domains. Don't really see how the dispute here
