Summary

This episode features Zach from Ontology, who demonstrates a neurosymbolic AI model that enables precise, real-time aesthetic search for e-commerce by learning from user mood boards without retraining. The hosts discuss how this approach offers greater trust and efficiency than traditional LLMs, which often hallucinate. The second half introduces Ashi Disanayaka of Spacium, a startup building in-orbit refueling stations. She explains their zero-boil-off technology and high-precision robotic actuators, which allow spacecraft to extend missions and carry more payload by refueling in space.
