Julia just isn't a replacement for Python yet. Recently did a deep dive researching various capabilities that would make Julia at least useful as a microservice/RPC target for a more I/O heavy language like Python. gRPC support is really poor. There's some OpenAPI/Swagger tooling, but it's not great. Likewise for ZeroRPC. The best candidate is probably the WebApi library [0] but even then, it does not inspire a ton of confidence for production. From cruising github issues and the Julia forums, nothing in this space (rpc/io/microservice) feels really bulletproof. Combined with no solid native executable support, it's just a nonstarter for me.

My gestalt sensation is the community is still too small, the tooling too unpolished, to be ready for anything production-worthy. If there were a bulletproof 0rpc library, I think it would go a huge way towards growing the community and mindshare through successive approximation. But the other problem is many of the folks on the forum seem totally disinterested in this problem.
