Yes, and that is the problem. It used to be if a product looked polished it was fairly polished engineering wise as well if we compare to todays AI slop. You can see that on steam, before AI slop games a game that looked polished mostly worked. But today you can get a game that looks like they put in a lot of effort, but its all AI slop and everything is flaky and broken, I've had way more such experiences the last few months than before that.

A human coder that was capable of coding a complex game typically also was good enough and tested things to make most things work. There were bugs etc, but at least buttons did things.
