A Hacker News post argues that Anthropic's new version control system, Scion, closely mirrors design ideas from Meta's Mononoke source control server, especially the use of derived data to speed up operations like blame. The post says the similarities go beyond shared prior art and notes that Mononoke was not credited, while also acknowledging that open-source systems can legitimately inspire later work.
