In this engaging discussion, psychologist Paul Bloom, a noted research professor at the University of Toronto, explores the complexities of utopia. He argues that our innate tribalism, jealousy, and preference for hierarchies make a perfect society elusive. Bloom reveals why struggles and scarcity can actually enrich meaning in our lives. He also highlights how legal frameworks can help counterbalance our biases while emphasizing gradual reform over radical change. Ultimately, he suggests that the pursuit of utopia should be viewed as a direction rather than a definitive endpoint.

In this captivating discussion, particle physicist Daniel Whiteson, author of *Do Aliens Speak Physics?*, delves into how alien senses might reshape scientific inquiry. He explores the idea of universal versus culturally shaped mathematics and how different intelligences might interpret fundamental truths. Whiteson also proposes an extended Drake equation for alien physics and examines the challenges of translating alien signals. With playful speculations on alien technology, he raises profound questions about our understanding of the universe and the nature of scientific progress.

In this discussion, neuroscientist Sergey Stavisky, co-director of the UC Davis Neuroprosthetics Lab, explores groundbreaking brain-computer interfaces (BCIs). He explains how paralyzed individuals can control robotic arms and regain speech through brain signals. The conversation dives into ethical concerns surrounding privacy and data ownership, as well as future possibilities of reading covert thoughts. Stavisky also shares insights on the engineering challenges and advancements, predicting that BCIs for communication may become a reality in just five years.

Bethanie Maples, a researcher in education and founder of Atypical AI, explores how science fiction acts as a cultural R&D lab.

Plus, ponder the possibility of civilizations lost to deep time, reminding us how easily history might slip away.

This week features Paul Bloom, a renowned psychology professor and author, who explores the complexities of loneliness and the role of AI companions. He discusses loneliness as a key biological signal that drives social connections and reveals the differing impacts of AI on the old versus the young. Bloom argues that while AI can provide comfort for isolated individuals, it might also hinder social growth by removing necessary challenges. The conversation tackles ethical implications of AI in human relationships, revealing both its promise and peril.

Cognitive scientist and linguist Steven Pinker dives into the nature of communication and common knowledge. He explores why people often use innuendo on dates and how it helps maintain relationships. Pinker discusses how shared beliefs shape society, touching on issues like cancel culture and mob behavior. He also explains how human emotions like blushing and laughter serve as crucial social signals. With insights from his book, he illuminates the complex interplay between language, awareness, and societal coordination.

In this engaging discussion, Ramesh Raskar, a professor at MIT Media Lab and an innovator in decentralized AI, shares fascinating insights about the evolution of intelligence in both humans and artificial systems.
