It's unreasonable to give up on explanations and deem something "not understandable" when we've been doing this thing for 3000+ years called mathematics, where it's exactly explainability that we seek and the removal of doubt.
The only other entities that we know of who can't communicate or explain what they're doing are animals.
It's fine if you want to refer to Kahneman's classification [1] of instinctual and thorough thinking. Explainability is a separate topic. Also when the amount of energy and compute used are as high as they are.. the results, the return on investment really isn't that high. Hopefully there are better days ahead.
