The author sides largely with Kelley, arguing that Anthropic's narrative — that AI is sufficient to replace software engineering — is driven by investor relations rather than technical truth. The Bun migration post is dissected for lacking honest tradeoff analysis, dismissing style guides without seriously attempting them, and contradicting itself on code readability. The author contends the real motivation for the rewrite was marketing Anthropic's Fable model, not genuine technical necessity. Multiple examples are cited showing that AI agents are not sufficient on their own, and that Anthropic's campaign to end software engineering is counterproductive. ## Full article daily.dev links to this article rather than hosting it.
