Anthropic's Scion is heavily inspired by Mononoke · sunshowers

Anthropic's new version control system, Scion, appears to heavily draw inspiration from Mononoke, as revealed in their description of "derived data" being used to enhance performance of operations like blames. This is reminiscent of a concept Anthropic's reporter had previously discussed in 2022 while working on a version control system called Mononoke, which was built with a team at Meta.

The reporter finds the level of imitation concerning, as Anthropic credits Claude for coming up with these insights, while Mononoke, which likely played a significant role, goes unmentioned. The reporter believes Anthropic's vision back in 2017-18 was powerful and enduring, but emphasizes that giving credit to previous innovations is crucial, especially with LLMs being able to easily identify prior art.
