Rachel Franklin, executive director at Harvard's Center for Geographic Analysis, and Patrick Johnson, EVP at Dassault Systèmes, dive into the world of digital and virtual twins. They explore how digital twins replicate complex systems, particularly in urban environments, and discuss industrial applications like those used in aerospace. The conversation also touches on ethical concerns around data privacy and surveillance, the need for interdisciplinary collaboration, and the potential of these technologies to improve elderly care and social connections.
