WT: Giving Powerful Topology 4

The episode is largely a discussion of ChatGPT/GPT-4 and how the hosts are using it in practice. Brian describes a hands-on experience role-playing as Blaine the Mono in GPT-4 and being impressed by how well it stayed in character, while Andrew explains the progression from GPT to GPT-2, GPT-3.5, ChatGPT, and GPT-4, emphasizing reinforcement learning with human feedback, instruction following, and stronger contextual understanding (L53-L61, L67-L69, L83-L85, L107-L118). The conversation also covers limitations and concerns: hallucinations and confident wrong answers, safety and guardrails, privacy/data-retention cautions, training data quality, and multimodal image features such as describing a refrigerator photo to generate recipes. The episode closes with picks for Welcome to the Monkey House, History of the World Part 2, Hello Tomorrow, Star Trek: Picard season 3, and a gel blaster/orbeez-style gadget discussed jokingly in the context of wildlife deterrence (L115-L118, L155-L177, L187-L209, L255-L269, L295-L297, L315-L317, L359-L365, L371-L405).
