Th author is not bearish on LLMs at all; this post is about using LLMs and code vs. LLMs with autonomous tools via MCP. An example from your set would be translation. The author says you'll get better results if you do something like ask an LLM to translate documents, review the proposed approach, ask it to review it's work and maybe ask another LLM to validate the results than if you say "you've got 10K documents in English, and these tools - I speak French"
