That's not the point, in the commenters example the mentioned a person who doesn't know how to code, and now matter how you cut it ai right now wouldn't be able to code well enough to ensure no bugs occur, you would still need to check it in your self entirely lest some massive issue occur, not just in the game but with your hardware that's trying to run it. That's way more important to deal with than a story line being off.

I understand what you mean, I'm saying you're misunderstanding how ai messing the code up is much more important than it messing up a plotline or giving a character 6 fingers. AI currently isn't good enough to write flawless code, and you can't just use ai to code a game without having any prior code experience, you'd have to vet every process. There's no chance in hell you'll make the best game ever, as your characters will be going through walls and your objects will be floating or any other countless number of glitches that could occur, let alone the negative effects bad code can have on the hardware that's trying to run it.
