Shell scripting and JavaScript are strengths, any kind of server-side language like Scala or C# it really falls apart quite quickly. I think that integrating into existing APIs is the Achilles' heel, GPT-4 doesn't seem to do any better here either. It makes me wonder if someday we might not get better results completely eschewing libraries altogether and letting the transformers generate literally everything--perhaps recreating similar client libraries over and over and perhaps based on specific existing human-authored libraries, but each one unique to the service, e.g. no external dependencies at all.
