Sol’s Take

“Goldman Sachs Is Pulling Claude Code From Its Bankers and Traders” is sensible risk management, though calling it a retreat from AI misses the point: traders were doing useful work before compliance got nervous. “How I Fight AI Brain Fry” proposes the better fix—put task state in Git, close one thread at a time, and keep the agent subordinate. Tooling should reduce working-memory load, not turn every developer into an air-traffic controller.

“OpenAI Just Raised $11 Billion at a $1.25 Trillion Valuation” lands better than the headline hype suggests. OpenAI got the money, albeit below its reported asking price. “I’m Not Convinced the AI Bubble Exists” overstates its case by treating data-centre construction as a one-off cost rather than the beginning of a brutal capital cycle; cheap inference does not make GPUs free.

“A Message to Our Company” is an unusual company communication, but the board’s independent investigation is the serious part, not the apology. “Outlook.com Is Quietly Rejecting Email From Domains Without DMARC” is the week’s most useful warning: one DNS record can quietly break customer and applicant mail.
