From my point of view there are 2 possible ways:

- we simply acknowledge we don't understand something enough and keep looking into it until we do. I mean everything we now understand (at an acceptable level by our standards) has gone through an intermediary phase - see alchemy for example.

- we declare some things (prematurely?) as forever escaping our grasp and accept we may never have a simple model of them.

What bothers me is the 3rd way:

- we don't know why but the computer model gave this result so let's go ahead with putting it into production. We make money, the user/consumer may have a nice experience or die, fingers crossed.
