Using tech you don't understand for yourself is one thing, and building things for other people you have no idea how you built is another.
Imagine if Ford or Tesla had no idea how to make cars and they just prompted an AI to build it.
You could make subpar cars that'll obviously kill their users, and you can do it for cheap too. I'm not denying it. Just pointing out they are really low quality , which is going to be bad for the he users.
