At a time when people are understandably focused on the daily chaos in Washington, these articles describe the rapidly accelerating impact that AI is going to have on jobs, the economy, and how we live. axios.com/2025/05/28/ai-…
🧵✨🙏 With the new Claude Opus 4, we conducted what I think is by far the most thorough pre-launch alignment assessment to date, aimed at understanding its values, goals, and propensities. Preparing it was a wild ride. Here’s some of what we learned. 🙏✨🧵

alternate history novel where Ask Jeeves became the dominant search engine, and now we’re all sending each other Jeevesmails, making spreadsheets in Jsuite, and instead of Google Glass we got the wildly successful Jeeves Smart Monocle
Something really encouraging about my project Modern Serial is that I haven't done any marketing for weeks, yet sales continue coming in every day or so. My suspicion is that people are learning about the site via word-of-mouth, but it's hard to know for sure.
