Musk’s $25B Chip Factory in Space, AI Collars Managing Cattle, OpenAI Doubling Its Workforce

Today we’re covering the biggest AI stories of March 23rd, 2026. Elon Musk unveiled Terafab, a joint Tesla-SpaceX-xAI chip facility that aims to produce 50 times the world’s current global compute output per year — with space-grade chips destined for solar-powered AI satellites launched via Starship, and Musk calling it the first step toward a “galactic civilization.” New Zealand startup Halter is nearing a $2 billion valuation backed by Peter Thiel’s Founders Fund, with its AI-powered cattle collars tracking 6,000 data points per minute and letting ranchers herd livestock remotely via app. Plus, OpenAI is reportedly planning to nearly double its workforce from 4,500 to 8,000 by year’s end, and a community workflow from a public sector manager who used AI as a career consultant and landed a €130K salary offer.
