The PSW crew discusses tips, tricks, and traps for using AI and LLMs. We discuss a wide range of AI-related topics, including how to utilize AI tools for writing, coding, data analysis, website design, and more! Some key takeaways include: AI has rapidly shifted from novelty to an essential tool in security and other fields. Paid AI versions offer significant advantages for professionals. Legal, ethical, and copyright questions around AI-generated content remain unresolved. Human skills, critical thinking, communication, and adaptability are more important than ever. AI is a powerful assistant, but not a replacement for expertise, creativity, or judgment. Fact-checking AI outputs and understanding bias are critical in the age of generative AI. This episode offers a comprehensive, practical, and philosophical look at how AI is reshaping security, education, and society, providing both optimism and caution for the future.
