Humanoid Robot Bubble Bursting: Expert Prediction
- Recent funding rounds, such as figure AI's $39 billion valuation as reported by TechCrunch on September 16, 2025, are fueling a surge in humanoid robot development.
- Roboticist Rodney Brooks, co-founder of iRobot and former MIT faculty, argues that attempts to replicate human dexterity in robots through video-based learning are fundamentally flawed.
- With approximately 17,000 specialized touch receptors, human hands possess a level of tactile sensitivity that current robotic technology cannot match.

The Limits of Imitation Learning
Recent funding rounds, such as figure AI’s $39 billion valuation as reported by TechCrunch on September 16, 2025, are fueling a surge in humanoid robot development. However, a leading voice in robotics is raising serious concerns about the viability of current approaches.
Roboticist Rodney Brooks, co-founder of iRobot and former MIT faculty, argues that attempts to replicate human dexterity in robots through video-based learning are fundamentally flawed. In a recent essay published on his website, Brooks characterizes this strategy as “pure fantasy thinking.”
The Challenge of Touch and Safety
The core issue lies in the complexity of the human hand. With approximately 17,000 specialized touch receptors, human hands possess a level of tactile sensitivity that current robotic technology cannot match. Unlike advancements in speech recognition and image processing, which built upon established data capture methods, a robust tradition for collecting and interpreting touch data is still lacking.
Beyond dexterity, safety presents a meaningful hurdle. Full-sized humanoid robots require significant energy to maintain balance, and a fall can be risky. The physics dictate that a robot double the size of existing models would possess eight times the potential for harmful impact.
A Future Beyond Human Form?
Brooks predicts that within the next 15 years, commercially triumphant robots will likely deviate considerably from the human form. He envisions designs incorporating wheels for efficient movement, multiple arms for increased functionality, and specialized sensors tailored to specific tasks.
Ultimately, Brooks believes that the current wave of investment is being directed towards expensive research experiments unlikely to yield scalable, mass-producible robots. This suggests a potential misallocation of capital within the robotics industry, prioritizing imitation over practical engineering solutions.
