I have read all of them and I have watched almost all of the training videos mentioned and that, is the list I would give anybody who I would want to discourage from joining the field. The textbooks I mean COME ON. They are comprehensive and neatly academic but not pragmatic at all. There are playlists in youtube that would cut through all the unnecessary content and will get you building RAG systems in a couple of hours. Kudos to the Langchain team for all the content online.
