The real bottleneck for robot dex hands: Hardware depreciation

Highlighting an analysis on human vs. robotic hands, a developer points out that while AI is making progress, physical hardware wear-and-tear might be the true bottleneck.
- Lifespan Limits: Today’s commercial dex hands cost $5k–$15k and advertise a lifespan of roughly 1 million manipulation cycles.
- Depreciation Cost: This implies a hardware depreciation of 0.5–1.5 cents per manipulation, before accounting for maintenance or downtime.
- Core Conclusion: For high-frequency, low-value tasks, the limiting factor may not be AI intelligence, but the cost per manipulation if wear costs approach the value created by the task.
