  • Ep36: DeepSeek AI – The Real Issue Isn't China, It’s AI Security
    2025/02/03

    AI Security and Competition: Unpacking the Debate Around DeepSeek

    This episode delves into the controversy surrounding DeepSeek, a Chinese AI considered by some as a national security threat. It questions whether this stance is legitimate or merely a tactic by big tech to stifle competition. The episode highlights multiple security breaches across the AI industry, including OpenAI and Google, arguing that the core issue lies in how AI handles security rather than its origin. The discussion also explores the suspicious uniformity in the anti-DeepSeek narrative, the potential motivations of big AI corporations to maintain monopolies, and the necessity of reading AI privacy policies. Additionally, the episode critiques the U.S. response to AI competition, drawing parallels to historical moments like the Sputnik era, and advocates for stronger AI security regulations and more open-source innovation. Listeners are encouraged to reflect on whether the fear of DeepSeek is justified or manipulated by big tech interests.
