Post author here. I think that's a great description of a "why" for this kind of setup.
I personally feel like with a lot of these emerging AI tools I still find myself still in the exploration phase. Trying to understand how they work and what they do, to then wrap my ahead around why I use them. Some of this post is a look into how I've been wrapping my head around the what and how of LangChain. Doing a follow-up digging deeper into the "why" and what benefits folks may see from this kind of setup is a really good nudge for me. Thanks!
