Today's window is dominated by AI infrastructure creeping into unlikely corners: Apple is repurposing idle Mac cycles for AI workloads, Anthropic had to replace Git itself to handle agent-scale commit volume, and open-source coding agents keep re-architecting around shared local services. Meanwhile Ramp's AI Index shows spend on OpenAI and Anthropic is brutally concentrated in a tiny sliver of firms, a data point worth weighing against any AI market hype. The chip supply chain gets two confirmations of tightness - a deep dive on TSMC's structural market power and ASML's record Q3 orders with 2027-2028 supply already strained. And for engineering leaders, a sharp essay on the decay of Amazon's writing culture is a good gut-check on whether your own org's thinking rituals survive scale.

• Apple's 'Minions' tech turns idle Macs into distributed AI compute
• Just 1% of firms drive 80% of OpenAI/Anthropic spend, per Ramp's AI Index
• Anthropic built its own VCS after AI agents pushed merges to 30,000/day
• TSMC's market dominance and ASML's record €11.7B quarter confirm chip supply is still tight
• Essay argues Amazon's famed narrative-writing culture has quietly eroded
