The central claim in this blog post hinges on there being no human review as part of the Bun rewrite. The actual postmortem describes the verification process in detail. Sumner monitored the workflows for most of the 11 days, manually reading outputs to catch issues and prompting Claude to fix the loop. It had multiple arounds of security reviews etc. I see the framing here a bit ingenuous.
Anthropic bot right here.
No, I am more than capable of reading and reaching my own conclusions.
Bold words for a throwaway.
