The same argument holds for "AI" too. We don't understand a damn thing about neural networks.
There's more - we don't care to understand them as long as it's irrelevant to exploiting them.
Yes, which is why the current explosion in practical application isn’t very interesting.

For some definition of “we”, I’m sure that’s true. We don’t need to understand things to make practical use of them. Giant Cathedrals were built without science and mathematics. Still, once we do have the science and mathematics, generally exponential advancement results.
