While LLMs dominate headlines, Dr. Fei-Fei Li argues that "spatial intelligence"—the ability to understand and interact with the 3D world—is the critical, underappreciated next step for AI. This capability is the linchpin for unlocking meaningful advances in robotics, design, and manufacturing.

The humanoid form factor presents significant safety hazards in a home, such as a heavy robot becoming a “ballistic missile” if it falls down stairs. Simpler, specialized, low-mass designs are far more cost-effective and safer for domestic environments.

For consumer robotics, the biggest bottleneck is real-world data. By aggressively cutting costs to make robots affordable, companies can deploy more units faster. This generates a massive data advantage, creating a feedback loop that improves the product and widens the competitive moat.

When building for AI-powered environments, design tools to be equally usable by humans and the AI model. An elegant, simple design for humans often translates directly into an effective tool for AI agents, simplifying development and promoting shared logic.

Progress in robotics for household tasks is limited by a scarcity of real-world training data, not mechanical engineering. Companies are now deploying capital-intensive "in-field" teams to collect multi-modal data from inside homes, capturing the complexity of mundane human activities to train more capable robots.

Initially, factories seemed like the easier first market for humanoids due to structured environments. However, Figure's founder now believes the home is a more near-term opportunity. The challenge of environmental variability is now seen as a data-bound problem that can be solved with large-scale data collection programs.

Contrary to public perception that advanced home robotics are decades away, insiders see tasks like cooking a steak as achievable in under five years. This timeline is based on behind-the-scenes progress at top robotics companies that isn't yet widely visible.

Automation in construction can do more than just lower costs for basic structures. Monumental's robots can create complex, artistic brick patterns and designs at the same speed and cost as a standard wall, potentially democratizing access to beautiful and diverse housing aesthetics.

AR and robotics are bottlenecked by software's inability to truly understand the 3D world. Spatial intelligence is positioned as the fundamental operating system that connects a device's digital "brain" to physical reality. This layer is crucial for enabling meaningful interaction and maturing the hardware platforms.
