If the hammer works when you hold it a certain way, that's great, but understanding all possible ways to hold a hammer doesn't always help get the nail in better. Is it true? I mean, in mathematics having a proof of something is way stronger than having a conjecture. And in engineering, proving that your solution is optimal is way stronger than saying "hey look, I tried many things and finally it works!". Worse, in statistics if you throw a bunch of tests and pick the one that "works" you might have false conclusions all the time. And AI is statistics. Sure it works to test out 10 datatset and whatever number of different machine learning, but it takes time and money and might be suboptimal from an engineering POV.
