AI-built bbtree claims fastest concurrent btree; researcher calls for ambitious academic systems

- A neat case study of AI for systems development: the author built bbtree, a foundation of databases and filesystems billed as the fastest concurrent btree, with code, blog post, and demo released openly.
- The recipe: (0) smart humans to understand and communicate the solution, (1) good metrics and cost models, (2) very basic swarms of agents writing code and tests to optimize those metrics.
- Takeaway: with AI now this capable, systems PhD students and academics can—and should—build extremely ambitious systems spanning large surface areas and evolve them in the open over a year or more.
