It's hard to decouple them as primary vs secondary because Julia is pretty central to what they're doing here. To my understanding, all the actual calculations that this is based on are in Julia, Dyad is basically a layer above it that gives a declarative interface, AI integration that understands that interface, and a GUI that makes it even easier (than the declarative language) to input the model. So funding for Dyad has pretty heavy incentives to go towards improving the Julia ecosystem because that's where its foundations are.
