Capital in Physical AI is splitting between commercial deployment platforms like Autonomous Solutions Inc. and Elroy Air, and early development modular robotics startups like Feather Robotics and O-ID.
Photonics drew money at both ends: PicoJool and Lightspring for optical links inside AI data centers, and Morphotonics for manufacturing waveguides for AI glasses.
