Langchain is one of the most hilarious libraries I've ever had the displeasure of looking through. Many of the abstractions look like they were written by a college student who took clean code way too literally. Many of the methods are so trivial and shallow that I'm shocked people use it in any serious capacity.

This. I was amazed opening something like PagagraphLineReaderFactory, thinking it somehow deals smartly with paragraph boundaries and too long paragraphs etc., and finding a trivial single line regex wrapped in two screens of OOP boilerplate.

I didn't feel the need to use Langchain, chaining LLM calls is usually just a few lines of code (I think even fewer than when using Langchain).
