Episode notes
Engineering Is Political Manipulation Of Space
- Engineers manipulate the natural world to advance a chosen 'mankind', which makes their work inherently political.
- Gareth frames engineering as the forceful, determinative manipulation of space where who counts as 'mankind' is decided by others.
Civil And Military Engineering Stayed Intertwined
- Military engineering and civil engineering remained porous roles into the modern era.
- West Point graduates built railways and fortifications, and Britain's chief railway inspectors were often former military officers into the late 20th century.
Engineers Are The Facilitators Of Policy Violence
- Engineers act as facilitators between policymakers and affected communities, not neutral bystanders.
- Gareth and Justin argue engineers draw the plans and implement slum clearances, highways, and waterworks that materially realize policy choices.
