### @physical-AI — Estimate — a stated framework hypothesis, grounded in primary pages
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.
