Perhaps this also explains why I almost think LLMs are not helpful in engineering-level projects:

1. My project involved programming languages and APIs that iterated several levels faster than LLM could publish a book

2. I have lost faith in LLMs developing software.

An example is the famous Unity game engine, but LLM has not helped its Unity DOTS architecture (ECS mode compared with GameObject mode). Although I have a basic understanding of it, both the entities API documentation and the LLM answers are terrible. I chose Unity because I heard it is mature so I think LLMs would be helpful with so much materials. Sadly, for ECS it doesn't. So I chose Bevy, a game engine that I can understand and apply by reading documents and can solve problems without the help of LLM.
