Even if we don’t understand the models themselves, you can still use them as a basis for understanding
For example, I have no idea how a computer works in every minute detail (ie, exactly the physics and chemistry of every process that happens in real time), but I have enough of an understanding of what to do with it, that I can use it as an incredibly useful tool for many things
Not the same. There is a difference between "I cannot understand the deeper details of certain model but some others can and there's the possibility of explaining it in detail" and "Nobody can understand it and there's not a clear cause-effect that we know" .
Except for weird cases, computers (or cars, or cameras, or lots of other man made devices) are clearly known and you (or another specialist) can clearly show why a device does X when you input Y on it.

Definitely interesting times!
