[hateful]

I would imagine, in this example, that the fact that you put in the numbers yourself gives you a mental map of where the numbers are and how they relate to each other, that having AI do it for you doesn't give you.

You could stare at a large sheet of numbers for a long time, and perhaps never get the kind of context you gained by entering them.

Additionally, if there was a mistake, it may not be as noticeable.
