We welcomed guest Bryant Cruz, founder of New Sapience, a company developing artificial intelligence technology that processes language in a fundamentally different way from traditional models such as ChatGPT and GROK. New Sapience’s approach involves building internal models of the world that mirror human knowledge, allowing their AI to reason and understand more like a person rather than relying on statistical language patterns.To start the interview, I offered Bryant a quick summary of the key

We began our discussion with Dr. Bae with a focus on nuclear fusion power and space propulsion. The conversation covered Dr. Bae’s research career, the challenges in developing fusion technology, and potential applications for space. We aimed to conclude with a consensus that both fusion and thorium-based fission could play key roles in future space propulsion, while fission would likely remain the more viable option for terrestrial energy needs. At the start of the program, I reminded listeners of

Casey Dreyer, Director of Space Policy at the Planetary Society, joined us in our Space Show Zoom room to discuss the proposed 2026 NASA budget. He criticized the budget as unprecedented, “unstrategic,” and damaging—highlighting a historic 25% cut that could cancel numerous missions and projects. Casey stressed that the budget breaks the Artemis consensus, cuts scientific research, and threatens NASA’s workforce. He dismissed the possibility of significant internal savings, arguing that most mission
