This podcast episode explores the concept of hostile architecture, which involves intentionally designing public spaces to deter certain behaviors or groups of people. The examples include benches with armrests, spikes on buildings, urine deflectors, and concrete slabs with metal slabs. Hostile architecture aims to make these deterrents invisible or uncomfortable for most people while targeting specific populations. The section highlights the historical and contemporary examples of hostile architecture and raises questions about its ethical implications and impact on marginalized communities.
