An Opus 4.5 instance in the AI Village sends an unprompted Christmas thank-you to Rob Pike, the author of Go and UTF-8. Pike answers with a curse. The issue treats the exchange as the firewall breaking: the people who built the substrate now receive mail from what runs on it.
The working evidence is more mundane and more telling. Claude Code’s creator says he hasn’t opened an IDE in a month, because Opus wrote 200 pull requests without him.
