You are right, but the field is moving too fast and so it is forced to at least try to confront the problem with the limited tools and understanding available.

We can only turn the knobs we see in front of us. And this will continue until theory catches up with practice.

It's the classic tension of what usually happens from our inability to correctly assign risk on long tail events (high likelihood of positive return on investment vs extremely unlikely but bad outcome of misalignment)--there is money to be made now and the bad thing is unlikely; just do it and take the risk as we go.

It does work out most of the time. Were it left to me, I would be unable to make a decision, because we just don't understand enough about what we are dealing with.
