Between April 2021 and April 2026, monthly retail and food services sales (adjusted for seasonal variations, holiday and trading day differences) increased by 24.3%. While that sounds like the economy must be humming along nicely, sales were essentially flat when adjusted for inflation. @StatistaCharts @uscensusbureau

We are not prepared for the uncharted housing market territory ahead of us We hear about the large boomer generation, their stake in US homeownership, and the coming “Silver Tsunami” But we don’t have any context for it Throughout history, generations passed on and their housing has recycled through the system to larger generations coming after them. Most households owned one home and there was never any flood of supply or pricing problems But there also has never been another generation that both A. Is this huge B. Owns so many US homes Boomers love houses How many of you have a boomer uncle or grandparent who owns 2, 3, 4 houses? Maybe a primary, a vacation home and rental too? Never before in US history has so much of the middle class of a generation owned multiple homes like this The number of 65+ households owning multiple homes has 5x’d since 1970 The resulting effect is that for ~1/5 boomer households that pass away, 2-3 properties may hit the market at once And the upcoming generations to absorb all these properties are not large in size and are not coupling at the same rate We’ve never lived through anything like this before











Codex hit 4M active users, less than two weeks after hitting 3M. We will reset rate limits today!











OpenAI pays $860K. Google runs 10 rounds. And most PM candidates are still prepping with frameworks from 2023. I've coached 200+ PM candidates. 30+ landed AI PM offers in the last 12 months. Five things shifted in the interview. First, they test whether you've built AI. "I understand transformers" used to pass. Now they ask you to walk through a production model that degraded and what you did. One candidate at Google: "They asked me what the F1 score was. I said I'd have to check. Interview was over in their minds." Second, vibe coding is a real round. Google, Figma, Perplexity. 45 minutes to build a working prototype in Cursor or Bolt. If you've never opened these tools, no framework saves you. Third, AI product sense replaced traditional product sense. Google removed the standalone technical interview for PMs. They want model-layer vs app-layer separation, safety without prompting, and prioritization with real math. Not "high/medium/low." Fourth, behavioral questions got specific. "Tell me about a failure" became "Walk me through an AI product decision you made that seemed right but you'd approach differently now." Generic STAR doesn't survive. Fifth, safety is tested everywhere. Anthropic has a dedicated round. OpenAI embeds it throughout. If you hit minute 40 without mentioning it, you've told them you don't understand the job. I recorded a full unedited mock with Dr. Bart Jaworski (12,000+ PMs helped, ex-Microsoft AI PM) showing how to handle all five: youtu.be/vPQCsAxWJ70
