I confirmed my understanding of "casual" by looking it up. Why would
this be a "limitation"?

Gosh, does the author of these lines really think that an GP mulls
over your body's chemistry before he or she prescribes something
against your headache?

Agreed, according to the definition of "shallow". That's not saying
that this is an entirely bad thing.

I'm not sure I understand your line of thought. "Planning" is a OR
discipline, but certainly not necessarily a way to solve a problem
such as prescribing medicaments.
