That was a lot of words to describe... I think just "LLMs use context"? And the intro made me think he was mad about something, but I think he's actually excited? It's very confusing.
It's a Steve Yegge article. His writing is enjoyable, but it's a miracle he wrote an article short enough not to skim. He's excitable and verbose.
Although he's talking up his product, it's an interesting premise. The idea is that cooking relevant context and parts from a codebase down into an LLM's context window, is a useful product for coding assistants.
I will admit, I skimmed. No jury would convict.
