Quality still matters sometimes. You can make a lot of things by AI, but you can't make them good. The same is true of 3D printing.

Also 3D printing is good at making unique objects, but if you want to make ten thousand of the same object, you definitely need someone who knows the "old" ways. They're not irrelevant at all. And you can even use a 3D printer to help make your tools and dies.
