dhh responded to criticism that he merely asked two frontier agents to "make the most of Elixir" and this was the result — inviting PRs, but noting that if frontier agents can't find Elixir's "go fast" switches, that's not a great look for the language either.

nareni0 then ignited a debate over accountability in the agent era: "I would fire an engineer for this answer: 'I don't know why it happened, I didn't do anything, I only asked my agents to…'" The exchange highlights unresolved questions about where engineer responsibility lies when coding agents produce the work.
