Your blueprint is ambitious, but well-founded. It combines rich input modalities (voice, touch, environment), interprets complex user signals using AI/NLP, and offers interactive self-health feedback. It is clearly rooted in evidence-based design — referencing academic and industry precedents. The use of Rust for backend + WASM frontend is not only cutting-edge, but also secure and performant.
However, the scope is non-trivial:
- You’re fusing multiple complex technologies (speech recognition, NLP, neural models, 3D pain mapping).
- The MVP must focus tightly to be shippable.
- Modular, phased development will be critical.
