CZ: Invested in artificial womb project, more optimistic about biotech than AI Binance founder CZ revealed in an interview with Galaxy that he’s currently more excited about biotech than AI and robotics— 'We all know AI will be huge, but it’s not as cool; biotech is more tangible, like actually solving everyone’s knee problems.' He disclosed that he has invested in an artificial womb company, which has completed the second trimester testing phase in mice. CZ estimates it will take another 5 to 10 years before it’s ready for human application. Additionally, he has also invested in an early-stage company that uses 3D-printed foam materials to repair knee cartilage. This company is preparing to enter human clinical trials.
