A Sunday show about doing your own arithmetic. Mustafa Suleyman gives the white-collar tier eighteen months, in a piece whose own counter-data sits two paragraphs down. The State of Brand argues every AI subscription is a subsidized loss-leader two weeks away from a forcing function. William Angel runs the tokens-per-hour math on an M5 MacBook Pro and finds OpenRouter cheaper. Frederick Vanbrabant uses The Goal to explain why agents move the bottleneck rather than break it. Marlene Mhangami's Playwright talk shows the cleanest pattern for tests AI should write. Calif's public M5 / MIE exploit write-up lands. Artem Loenko explains why every chat UI keeps ending up on a browser engine. And Luke Lanchester's MCP hello page is the small fix I most enjoyed this week.
