Buf's offering of protobuf registries and codegen SDKs for microservices seems less necessary in the LLM era.
I'm starting to question many of protobuf's advantages (perhaps not the wire format). Add to that monorepos and other fads of the 2010s given the rise of LLMs.
I used to be a big believer in this stuff, but I'm quickly having my core assumptions change out from under me.
The real argument shouldn't be about protocols becoming obsolete, but programming languages that are "less efficient" could eventually become obsolete in favor of highly scalable and performant languages due to LLMs when the main gap becomes knowing how the tech works at a high level, and not the syntax, why code in one language over another if you don't need to worry about messing up on syntax, only about reviewing logic for sanity and correctness against business rules as well as validating that it is stable code.
I feel exactly that way about REST. The assumption that LLMs make schemas obsolete misses how structured outputs actually work in production. When you have probabilistic models generating code, strict contracts become more critical, not less. It is no coincidence that several major LLM platforms rely on ConnectRPC and Protobuf for their own APIs.
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.
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.

Perhaps we need new tools for this going forward.
