This Week in Open Source for 09/19/2025

A look around the world of open source

by Daryl Ducharme & amanda casari, Google Open Source

As we enter the Autumn of 2025, AI is still on the top of everyone's mind in tech and the world of open source is no different. This week we delve into various facets of AI's impact on the open source world, from its presence in the Linux kernel and the need for official policy, to the discussion around copyright in AI and how it affects open source licenses. We also explore ways companies can actively support open source, the challenges federated networks like Mastodon face with age verification laws, and the emerging concept of spec-driven development with AI as a design tool.
