Julia's Broadcast vs Jax's vmap

The fact that we trace to IR using dispatch (and so much of Python isn’t available for overloading) significantly restricts the information we can get out of the source language.

Aside the practical aspects of things like Python have a MUCH larger user-base etc etc. I wonder, purely on a techncial idealised world. Would implementing JAX on Julia result in a much more technically superior product. Just wondering out loud.
