This is not quite like that but the feeling I get from it is much the same. Mathematicians are first and foremost busy with understanding math, not with 'solving' math though they are solving individual problems within the domain of math. The journey towards that understanding requires specialization and often lots of studying.
To quote Douglas Adams: "If 'metal nose' here is going to give you God's phone number then the philosophical question of whether there is a God becomes meaningless."
It is the journey and the questions that matter as much or more than the answer does.
And with math being a branch of natural philosophy I can see why they would be a tad upset at this shortcut because it strips the collective efforts of a large number of people of their prestige and feeling of time well spent. Imagine your life's work reduced to a short string of bits, and worse, that short string of bits was created by a machine that effectively is still a toddler.
