Every interesting problem sits between two departments. Here is the one kind of person who lives there.
Situation wanted
Has read outside the field. Will connect your two teams that do not speak. Comfortable being the least specialized person in the room and the only one holding the whole picture.
Previous experience: several fields, none finished, all still in use. No references from a single discipline available, by design.
apply to: any problem that does not fit a job description
The fashionable ask is depth in one thing plus "some breadth." But the problems that matter are not shaped like a T. They live at intersections nobody owns, in the gap between the two experts who each assumed the other had it.
History's polymaths did not master everything. They connected everything. The notebooks jump from anatomy to hydraulics to optics, and the jumps are the point. The value was never in any single page.
Every field you enter opens doors into the fields beside it. Specialists guard one door. Generalists walk through more of them, and come back describing rooms the specialists did not know were adjacent.
Problems in want of a generalist
We are not saying specialists are wrong. We are saying somebody has to notice the fire is in a different department.
The world rewards specialists. It is held together by the people who move between them.
