The conversation centers on the accelerating transition from digital AI to physical systems, drawing on Caitlin Kalinowski’s experience across Apple hardware teams, Meta’s VR and AR efforts, and OpenAI’s emerging robotics work. It frames robotics and embodied AI as the next frontier once keyboard-based capabilities plateau, while detailing concrete engineering, supply-chain, and organizational practices required to build at scale.

Drivers of the hardware shift

Caitlin describes a shared realization in AI labs that progress in software models will eventually saturate. Once digital systems handle complex reasoning at high speed, the remaining bottlenecks move to sensing, actuation, and manipulation in the physical world. This includes autonomous vehicles, drones, manufacturing cells, and humanoid robots. Technologies first matured for VR and AR—SLAM positioning, depth sensing, and spatial understanding—now transfer directly to robot navigation and control. The same actuator and magnet supply chains that support drones also underpin robotic arms, creating overlapping constraints across consumer devices, industrial equipment, and defense applications.

Show Notes

Caitlin Kalinowski was most recently at OpenAI helping build their robotics and hardware teams from scratch. Prior to that, she was head of AR glasses and VR hardware at Meta, where she led the teams building every generation of the Quest, Rift, and Orion, and was Meta’s first consumer electronics hire. Before this, she was technical lead on MacBook Air and Mac Pro at Apple, and helped engineer the original unibody MacBook Pro. She’s designed and engineered some of the hardest and most beloved consumer hardware products in history and is now focused on the next frontier: robotics.

In our in-depth conversation, we discuss:

1. VR—what happened?

2. The coming memory price shock and why she’s telling startups to pre-buy now

3. How the technologies built for VR became the foundation of modern warfare

4. Why humanoid robots are still just prototypes, and what’s actually gating mass deployment

5. Lessons from Steve Jobs, Mark Zuckerberg, and Sam Altman

6. Why she left OpenAI
