Anthropic has agreed to pay SpaceX nearly $45 billion over the next three years for compute resources. It will pay $1.25 billion per month until May 2029, with either party being able to end the agreement with 90 days' notice. The companies had earlier this month inked a deal that gave Anthropic 300 megawatts of computing capacity from a large SpaceX data center in Memphis known as Colossus 1. This partnership has expanded to include capacity at a second SpaceX data center.

Activity-focused design centers on the actions people take to reach their goals, with the core unit of analysis being what people do and how they do it. Task analysis is one approach that breaks down user goals into activities and individual tasks, requiring designers to choose appropriate levels of specificity for their design context. The process involves first identifying the most important user goals, then determining the specific tasks needed to achieve them.
AI is pushing designers beyond simply creating screens and assets toward designing workflows, systems, and organizational processes around AI itself. The biggest opportunity isn't just working faster with AI tools, but becoming someone who shapes how AI fits into products, teams, and business decisions — turning design into a more strategic, systems-focused role rather than a purely production-focused one.
