Can it generate good code?

Both the author and I agree in that yes, it can.

Does it always generate good code?

Here is where the author and I disagree vehemently. The author implies that the ai-generated code is always correct. My personal experience is that it often isn't. Not even for big projects - for small bugfixes it also misunderstands and hallucinates solutions.

So no C or assembly for me, thank you very much.
