I used to be very optimistic about Julia, but my enthusiasm has really cooled off the last year. I find JAX+jax_dataclasses gives me 90% of what I wanted from Julia (a nice monad library that is compatible with jit’ed code and the ability to cache compiled code would make it a solidly better language).
I don't know whether the monad library is nice but caching compiles code is something they are making great progress on. Veraion 1.9 seems able to store most compiled code on disk.
But then there's not enough users... so the cycle continues until one day Julia hits critical mass and a tipping point is reached.
