🏗️ Stargate Reshuffles: Microsoft Takes Over Texas Data Center After OpenAI Backs Away

Microsoft is stepping in to build two AI factory buildings in Abilene, Texas — right next to OpenAI’s Stargate campus — after OpenAI dropped expansion plans. Data center developer Crusoe is working with Microsoft on the new buildings plus an on-site power plant. The two former partners are now literal neighbors pursuing AI development separately, despite Microsoft still holding ~27% of OpenAI.

💡 Karpathy: The Real Challenge for AI Agents Is DevOps, Not Code

Andrej Karpathy argued that building an app with AI is easy — the hard part is the “IKEA furniture assembly” of services, payments, auth, databases, domain names, and deployment. He envisions a future where agents handle the entire DevOps lifecycle end-to-end, from reading docs to getting API keys to deploying to production — no human clicking required.
