Similarly to this post, I think that the "good" abstractions handle application logic (telemetry, state management, common complexity), and the "bad" abstractions make things abstract away tasks that you really need insight into.
This has been a big part of our philosophy on Burr (https://github.com/dagworks-inc/burr), and basically everything we build -- we never want to tell how people should interact with LLMs, rather solve the common problems. Still learning about what makes a good/bad abstraction in this space -- people really quickly reach for something like langchain then get sick of abstractions right after that and build their own stuff.
