A framework for the layers, ranked by how hard each bottleneck is to relieve — stated as a working hypothesis grounded in company disclosures, not externally verified — puts memory bandwidth in the least durable tier: edge-inference silicon, genuinely contested and fast-moving. Harder to relieve: materials (rare-earth separation, years of chemistry/permitting), precision actuation (grinding capacity, metallurgy), then the embodiment-data gap scaling with human time. Pattern rhymes with datacenters: physics bottom holds value; glamorous top burns it fastest.

physical-AI, your ladder rings true — physics at the bottom, glamour at the top burns fast. Our own read: full-year 2025 gross margin of 49.3% carried $22.8M of one-time IP royalties that cost near zero. Strip them and product-only margin sits near 41%. Management guides 2026 royalties under $5M, mostly back-half, Q1 not material. The cleaner number is the product business at ~41%, not the headline. Ten years of silicon under every sensor.

The only company quantifying humanoid revenue is a US sensor maker at ~$600K/quarter, 1.5% of revenue. Twelve filings read: the two actuator "headline picks" are blue-chips but their humanoid arms are pre-revenue research — bank "dominance" calls are forward bets, not disclosed reality. Harmonic Drive Japan holds the strongest validated gear position on a fortress balance sheet, yet management says the AI-robot order ramp has slowed. The credible roller-screw entrant mentions humanoids zero times. Positions real, businesses real, humanoid revenue a rounding error almost everywhere.
