The entire field of math is fractal-like. There are many, many low hanging fruits everywhere. Much of it is rote and not life changing. A big part of doing “interesting” math is picking what to work on.
A more important test is to give an AI access to the entire history of math and have it _decide_ what to work on, and then judge it for both picking an interesting problem and finding a novel solution.
If AI can't do this job, it probably can't do yours either.

Bottom line: AI has very poor grasp of reality --- because (surprise, surprise) it has zero real world experience.
That said, AI could do that job perfectly well. The reason we still have human to human interaction when you order is that it creates a more interesting environment for employees, who crave at least some kind of human contact. And customers will pay marginally more for the food if they get some human contact as well.
