> AI “writes bad code,” “introduces bugs,” “creates technical debt,” or something along those lines.

It is strange to me that your question is so narrowly scoped, as though code is the only current use of AI and as though bugs are the reason to be against it and not a clear existential crisis that the world has not demonstrated any capability to meet.

The end goal of AI, literally the goal, is to make it so that workers aren't needed anymore. Ignore for the moment that AI isn't good enough right now to have eliminated all the worker roles yet. That is still fundamentally its goal. You will tell the AI what you want, the AI will give you what you want, ..., profit. No nasty employees to deal with.

I would rejoice at this if I lived in a society that decided it would use the fruits of each new labor efficiency to provide for the populace instead of telling me that people who don't work should die in a gutter. But I do not live in such a society.
