I agree with the author. My work involves designing simulations for control. Yesterday, I asked GPT-4o to write a python-only simulation for a HVAC system (cooling tower, chiller on the water side, and multiple zones with air handling units on the air side).

It wrote functions to separately generate differential equations for water/air side, and finally combined them into a single state vector derivative for integration. Easy peasy, right?

No. On closer inspection, the heat transfer equations had flipped signs, or were using the wrong temperatures. I'd also have preferred to have used structured arrays for vectors, instead of plain lists/arrays.

However, the framework was there. I had to tweak some equations, prompt the LLM to re-write state vector representations, and there it was!

AI-assisted coding is great for getting a skeleton for a project up. You have to add the meat to the bones yourself.
