The ‘metaverse’ and its so-called ‘virtual worlds’ have somewhat fallen short of the hype, but that doesn’t mean everyone has lost out. Urban planners across the globe have started to combine the vision of the metaverse with smart cities and the internet of things, to create immersive ‘digital twins’ of our cities and buildings that are changing how we think about urban planning. In this episode we speak to Salla Eckhardt, Senior Vice President for Commercial Market at OEC Services who formerly worked with Digital Twinning software at Microsoft, and Anders Logg, Professor of Mathematics at Chalmers University in Sweden, who develops and explores digital twins for cities.
