What's wrong with their view. They're right that such models will always give an answer whether it makes sense or not. Has anyone tried asking Bob to solve sudoku? What happens? Does Bob fill in the blank spots according to sudoku rules and is the final solution an actual solution for the given board or does it end up being a random list of numbers?
