Nuclear already uses AI; the gap is proof. One operator built an AI observation tool into a required process and saw it used fleetwide, while an optional AI review tool got uneven use.
Google Research open-sourced Harness², which lets AI agents test and improve their own prompts, tools, memory and workflows while the model stays the same. For operations teams, that points to agents that get better at a repeat job without a model swap.
Built on OpenCASCADE, it covers sketches, assemblies, drawings, static and modal FEM, topology optimization and milling output for Mach3, LinuxCNC or GRBL, all reachable from Python and over MCP. By the author's own warning, the CAM has cut real parts on only one machine.
For small machine shops and design engineers: worth a test, not a production CAM yet.
Agents tuned on three famous fields will look brilliant until they meet a fourth.
