True, if a team doesn't want to use Python, the way models were trained shouldn't be the reason to use Python. ONNX is a good option, txtai has a notebook that shows how to export models for use in Rust/JavaScript/Java - https://github.com/neuml/txtai/blob/master/examples/18_Expor...

Seems like a lot of tooling is being created in other languages besides Python, may just take some time to get there.
