That’s the opposite of what OP is observing. It’s easier to teach a domain expert “good enough” quantitative and technical skills than to teach a pure quant “good enough” domain expertise (and the corresponding intuition)

I think you’re reading this backwards, or perhaps it was edited? Mathematics is surely the more pure discipline compared with economics, so physics : CS :: mathematics : finance is the right ordering.

You just decided that one of those expertises is the "domain" while the other is not. There's no reason at all to pick one of them.

and it's easier yet to find one of each that are willing to collaborate.
