The episode returned to Anthropic’s new AI watermarking system with much more detail about how it will work. Anthropic says new Claude models will add machine-readable marks to generated content as part of its commitment to EU transparency rules, including output from Claude, Claude Code and its API. But Anthropic also warns that detecting a mark does not prove Claude authored the material. Claude may have only proofread, translated or summarized it, while heavy editing can also remove the mark. That raised a larger question: if AI eventually touches almost everything people write, what does detecting an AI watermark actually prove? The discussion then shifted to the growing revolving door at major AI labs, including Brad Lightcap leaving OpenAI and prominent researchers using their experience and wealth to launch new AI companies. Google also reportedly passed one billion Gemini users. The hosts returned to frustrations with Opus 5 and discussed why some users are shifting toward Codex, particularly because the broader ChatGPT app offers smoother browser use, scheduled tasks and automation. Grokbot’s release added another example of always-on agent teams with their own cloud computers, leading to a broader discussion about AI coworkers that can coordinate information across email, documents, transcripts and workplace chat. The final section covered China’s much larger planned electricity buildout for AI infrastructure, Target appointing its first chief AI officer, Perplexity blocking Time’s markdown-based ads aimed at AI agents, and how large publishers blocking AI crawlers may give smaller websites a surprising advantage in AI search.
