All the world's a robot-staging ground for tech entrepreneurs building 'physical AI'

Computer scientists are shifting focus from large language models to AI "world models" as the next frontier, recognizing limitations in current chatbot technology. Entrepreneurs are building physical AI systems that can interact with and understand the real world.

The Atomic take

The pivot toward world models reflects a hard truth: chatbots can predict text but cannot reliably reason about physics, space, or cause and effect, which is exactly what robots need to operate safely in warehouses and homes. The bet here is that training AI on how the real world behaves will close the gap between impressive demos and machines that actually function outside the lab. Watch which entrepreneurs ship working hardware versus those still selling the vision, because the difference will separate funded survivors from the next wave of failed robotics startups.
