CISO Perspectives (public) N2K Networks This season on CISO Perspectives, host Kim Jones explores some of the challenges of leading through uncertainty. We explore the complexity of the changing nature of regulation and working with the federal government, the evolution of privacy and fraud, and how emerging technologies like AI and quantum computing are changing cyber. When you don’t know what questions to ask, you’re afraid to ask, or don’t know who to ask, CISO Perspectives provides the foundation for learning in this brave new world. Things of Interest Serena Chen & Sophia Frentz Things of Interest is hosted by Serena Chen and Sophia Frentz, and is a podcast that encompasses, in its purest form, things that we find interesting. Our discussions often center around technological advancements and how they affect social issues. As two socially-conscious millennial nerds, who is better placed to talk about artificial intelligence, leadership, bitcoin, quantum computers, gene editing, and fandom? Probably no-one.fandom? Probably no-one. Tech Talks Daily Neil C. Hughes If every company is now a tech company and digital transformation is a journey rather than a destination, how do you keep up with the relentless pace of technological change?Every day, Tech Talks Daily brings you insights from the brightest minds in tech, business, and innovation, breaking down complex ideas into clear, actionable takeaways. Hosted by Neil C. Hughes, Tech Talks Daily explores how emerging technologies such as AI, cybersecurity, cloud computing, fintech, quantum computing, Web3, and more are shaping industries and solving real-world challenges in modern businesses.Through candid conversations with industry leaders, CEOs, Fortune 500 executives, startup founders, and even the occasional celebrity, Tech Talks Daily uncovers the trends driving digital transformation and the strategies behind successful tech adoption. But this isn't just about buzzwords. We go beyond the hype to demystify the biggest tech trends and determine their real-world impact. From cybers Rationality: From AI to Zombies Eliezer Yudkowsky What does it actually mean to be rational? The kind of rationality where you make good decisions, even when it's hard; where you reason well, even in the face of massive uncertainty; where you recognize and make full use of your fuzzy intuitions and emotions, rather than trying to discard them. In Rationality: From AI to Zombies, Eliezer Yudkowsky explains the science underlying human irrationality with a mix of fables, argumentative essays, and personal vignettes. These eye-opening accounts of how the mind works (and how, all too often, it doesn't) are then put to the test through some genuinely difficult puzzles: questions in computer science about the future of artificial intelligence (AI), questions in physics about the relationship between the quantum and classical worlds, questions in philosophy about the metaphysics of zombies and the nature of morality, and many more.
