An SCI-style exposition of AI’s end-state and near-term transformation: a dual-layer architecture of an Environmentalized Intelligence Layer plus a Personal OS, grounded in structured world models, neuro-symbolic fusion, embodied loops, and trustworthy governance.

Upgrade prompts into interaction protocols: roles, state, tools, memory, and evaluation loops.

From product to platform: developer network effects, supply‑chain coordination, and governed openness.

From assistance to collaboration: multimodal fusion of imaging–pathology–clinical data and workflow redesign.

Key hardware and system trade‑offs: general‑purpose GPUs, specialized NPUs/ASICs, near‑memory, and distributed orchestration.
