In October 2026, Caroline Marvin, a 78-year-old emeritus professor at the University of Pennsylvania located in Philadelphia, USA, repeatedly obstructed the path of Uber Eats' Serve food delivery robots, refusing to move aside. Ultimately, she was arrested by the police for disturbing public order. Marvin explained that her actions were a form of protest against the use of automation technology to replace human delivery workers. She contended that companies are boosting their profits by cutting labor costs, all the while disregarding workers' rights. Despite her arrest, Marvin remains steadfast in her resolve to continue her protest, asserting that it constitutes a protected activity under the First Amendment of the U.S. Constitution. This incident swiftly garnered widespread attention via social media and news reports, highlighting the tensions that can arise between automation technology and the communities and workers affected by its implementation.
