I work on firmware and deep embedded systems. Trust me when I say LLMs are getting just as capable in this domain. Eg LLMs can do RF filter design. Tell the LLM your target metrics and it will give very reasonable design constraints, especially when you come back with simulation results and relevant feedback.
Right, but that is self contained domain. Hook it up to anything and an impedance mismatch will offset the intent of your poles. Failure modes, cross domains, integration, loads, design intersections; AI can build components, but its the sprouting of these components that exponentially magnifies the number of failure modes.
Engineering needs to be failure free, or at least failure preventive via redundancy, and the latter requires the same full systems understands as the former
