Are there any cool formats to learn how to build AI products or Langchain specifically?

Hey folks! Interested, how everyone here learned how to build AI products? Right now the major way to do so is Langchain — https://langchain.com/ I'm thinking about launching gamified platform to learn it — here s a trailer for it: https://twitter.com/AlinaRokaru/status/1721850245355540734 Looking for ways how people already learning Langchain or general development LLM-based products? Why there should be ways : 1/ Huge entropy — right now I know a lot of techniques: prompt engineering, agents ensemble, memory patterns with vectors, graphs, etc. Too many problems, and no organized ways of learning. 2/ Poor analogies — current ways learning materials try to explain all these concepts are poor [imo]. No clear and straightforward analogies with what is chains, what are agents, etc. for new learners of these concepts. What do you think?
