I think i will have to disagree.

When you are not making a simple website, but an actually enterprise system, AI just simply can't do that without making any bugs or start to hallucinate.

Even if debugging changes significantly, testing still seems unavoidable for validating system behavior.

"I’ll end with this. I majored in computer engineering. I know how to design an 8-bit microprocessor on FPGAs. . .in the late 1990s. Do you think I fully understand the Apple M4 chip in the laptop I’m writing on? Conceptually, yes—I understand the principles. But I don’t know everything it’s doing, instruction by instruction. And that’s fine."

sorry, but you're talking about abstractions painstakingly studied, designed and developed by a human being. That is NOT comparable to unexamined regurgitations and hallucinations of an AI.
