According to @ai_darpa, a new AI-powered simulation demonstrates a gear system with extreme ratios, where the final gear rotates slower than the age of the cosmos. This showcases the power of advanced AI algorithms for computational modeling, optimization, and simulating highly complex mechanical systems. Such AI-driven simulations enable engineers to visualize unprecedented mechanical configurations and explore new business opportunities in robotics, industrial automation, and precision manufacturing by reducing prototyping costs and accelerating innovation (source: @ai_darpa, Jan 4, 2026).
