AI Changed Everything
Before 2023, humanoid robots were expensive research toys. The arrival of vision-language AI models gave robots the ability to understand and follow instructions. Goldman Sachs cited "AI progress surprised us most" when revising their forecast upward by 4×.

China Is Winning on Units
Chinese manufacturers — led by Unitree Robotics — shipped 87% of 2025's humanoid units by volume. The Unitree G1 at $16,000 is 15× cheaper than the Boston Dynamics Atlas. Volume wins eventually.

Factory First, Home Later
Every major deployment so far is industrial: BMW (Figure), Amazon (Agility Digit), Hyundai (Atlas). The factory is the beachhead. Goldman's base case assumes consumer adoption comes 2–4 years after industrial tipping point.

Following the Cost Collapse Playbook
Solar panels fell 99.7% in 45 years. EV batteries fell 97% in 15 years. Humanoid robot hardware is on a similar deflationary curve — driven by actuator and sensor scale. Tesla targets $20K, down from $250K+ today.

The Battery Bottleneck
Most humanoids run 2–5 hours per charge. Tesla Optimus Gen 2 leads with 10–12 hours. For a factory to run 3 shifts, it needs either robots with 24hr batteries or a hot-swap infrastructure. This is the unsexy problem nobody is solving fast enough.
