It probably helps that Julia and Fortran are both column major.

When interfacing with C languages, that can be a big penalty (depending on the complexity of the algorithm).

It will probably take two generations of developers to make this happen, but well worth it. When I was studying atmospheric science I tried to understand OpenWRF (weather research forecasting) and the barrier was too high... And I had programming experience, imagine those with none!

An open source project is only as useful as it is accessible to it's average developer base.
