Mechanical Sympathy
3 July 2026
Mechanical Sympathy was term coined by Sir Jackie Stewart, a three-time Formula 1 World Champion, to describe the understanding a driver needed to have for a car's capabilities in order to drive it well. That term was then imported into software development by Martin Thompson. Thompson's view was that developers need a rough understanding of the hardware in order to create efficient software.
Unmesh Joshi expanded this concept by describing how Expert Generalists share a characteristic of having a sympathy for domains related to their work.
