Even if AI magically got to the point of providing accurate and good results, I would still profoundly object to using it.
First, it's a waste of resources. The climate impact of AI is enough of a reason why we should leave it dead until we live in a world with limitless energy and water.
Second, I don't trust a computer to select my sources for me. Sometimes you might have to go through a few pages, but with traditional search engines at least you are presented with a variety of sources and you can use your god given ability of critical thinking.
