You're right, but the adeptness of models to spin up clients and behaviors on the fly is remarkable. They're capturing the semantics of behavior at a deeper level.

If we do strict schemas, I'd like to see less ceremony around them. Tool calls instead of brittle build steps and protocol registries.

Perhaps we need new tools for this going forward.

Hm... Maybe. In my view, an IDL is part of the input that you absolutely want humans to author or carefully review at least. In my experience, the ceremony around generating code is also performed very well by LLMs. But I do agree, there's definitely some changes that are needed to integrate Protobufs better. Some languages have built-in tooling to make it seamless, but it's definitely not universal.

why? are humans going to stop using services?
