on a Zoom call with Wanyu He, an architect based in Shenzhen, China, and the founder of XKool, an artificial intelligence company determined to revolutionise the architecture industry. She freezes the dancing blocks and zooms in, revealing a layout of hotel rooms that fidget and reorder themselves as the building swells and contracts. Corridors switch sides, furniture dances to and fro. Another click and an invisible world of pipes and wires appears, a matrix of services bending and splicing in mesmerising unison, the location of lighting, plug sockets and switches automatically optimised. One further click and the construction drawings pop up, along with a cost breakdown and components list. The entire plan is ready to be sent to the factory to be built.
