To biologists in this field, I suspect this statement reads something like “this is the first Python client for our Node gRPC service, we have no idea if the language interop will work”.

It ignores all of the hard work over literal decades that has gone into the work of developing mRNA-based medicine (gRPC and protobufs), which was developed literally for situations like Covid-19 (polyglot services communicating over network interfaces).

Yes, mRNA is basically magic from a distance. So is all of modern technology. But it’s built on and hardened by iterative experiments, not conjured from thin air.
