Café Zai is a 20-minute podcast where urgent conversations meet real action. Hosted by architect and systems thinker Kimon Onuma, FAIA, each episode brings together doers and disruptors from architecture, digital twins, BIM, GIS, AI, semantics, and beyond, all sitting at the same virtual table. No slides. No scripts. Just sharp dialogue and real work behind the scenes. From digital twins to standards to resilience, we connect the dots. You’re invited to listen in, and when you’re ready, pull up a chair. This is Café Zai.
